DESCRIPTION
    Moose is an extension of the Perl 5 object system.

    The main goal of Moose is to make Perl 5 Object Oriented programming
    easier, more consistent, and less tedious. With Moose you can think more
    about what you want to do and less about the mechanics of OOP.

    Additionally, Moose is built on top of Class::MOP, which is a metaclass
    system for Perl 5. This means that Moose not only makes building normal
    Perl 5 objects better, but it provides the power of metaclass
    programming as well.

  New to Moose?
    If you're new to Moose, the best place to start is the Moose::Manual
    docs, followed by the Moose::Cookbook. The intro will show you what
    Moose is, and how it makes Perl 5 OO better.

    The cookbook recipes on Moose basics will get you up to speed with many
    of Moose's features quickly. Once you have an idea of what Moose can do,
    you can use the API documentation to get more detail on features which
    interest you.

  Moose Extensions
    The "MooseX::" namespace is the official place to find Moose extensions.
    These extensions can be found on the CPAN. The easiest way to find them
    is to search for them (<https://metacpan.org/search?q=MooseX::>), or to
    examine Task::Moose which aims to keep an up-to-date, easily installable
    list of Moose extensions.

TRANSLATIONS
    Much of the Moose documentation has been translated into other
    languages.

BUILDING CLASSES WITH MOOSE
    Moose makes every attempt to provide as much convenience as possible
    during class construction/definition, but still stay out of your way if
    you want it to. Here are a few items to note when building classes with
    Moose.

    When you "use Moose", Moose will set the class's parent class to
    Moose::Object, *unless* the class using Moose already has a parent
    class. In addition, specifying a parent with "extends" will change the
    parent class.

    Moose will also manage all attributes (including inherited ones) that
    are defined with "has". And (assuming you call "new", which is inherited
    from Moose::Object) this includes properly initializing all instance
    slots, setting defaults where appropriate, and performing any type
    constraint checking or coercion.

PROVIDED METHODS
    Moose provides a number of methods to all your classes, mostly through
    the inheritance of Moose::Object. There is however, one exception. By
    default, Moose will install a method named "meta" in any class which
    uses "Moose". This method returns the current class's metaclass.

    If you'd like to rename this method, you can do so by passing the
    "-meta_name" option when using Moose:

        use Moose -meta_name => 'my_meta';

    However, the Moose::Object class *also* provides a method named "meta"
    which does the same thing. If your class inherits from Moose::Object
    (which is the default), then you will still have a "meta" method.
    However, if your class inherits from a parent which provides a "meta"
    method of its own, your class will inherit that instead.

    If you'd like for Moose to not install a meta method at all, you can
    pass "undef" as the "-meta_name" option:

        use Moose -meta_name => undef;

    Again, you will still inherit "meta" from Moose::Object in this case.

EXPORTED FUNCTIONS
    Moose will export a number of functions into the class's namespace which
    may then be used to set up the class. These functions all work directly
    on the current class.

  extends (@superclasses)
    This function will set the superclass(es) for the current class. If the
    parent classes are not yet loaded, then "extends" tries to load them.

    This approach is recommended instead of "use base"/"use parent", because
    "use base" actually "push"es onto the class's @ISA, whereas "extends"
    will replace it. This is important to ensure that classes which do not
    have superclasses still properly inherit from Moose::Object.

    Each superclass can be followed by a hash reference with options.
    Currently, only -version is recognized:

        extends 'My::Parent'      => { -version => 0.01 },
                'My::OtherParent' => { -version => 0.03 };

    An exception will be thrown if the version requirements are not
    satisfied.

  with (@roles)
    This will apply a given set of @roles to the local class.

    Like with "extends", each specified role can be followed by a hash
    reference with a -version option:

        with 'My::Role'      => { -version => 0.32 },
             'My::Otherrole' => { -version => 0.23 };

    The specified version requirements must be satisfied, otherwise an
    exception will be thrown.

    If your role takes options or arguments, they can be passed along in the
    hash reference as well.

    You should only use one "with", even if you are consuming multiple
    roles. If you consume roles using multiple "with" statements Moose
    cannot detect method conflicts between those roles.

  has $name|@$names => %options
    This will install an attribute of a given $name into the current class.
    If the first parameter is an array reference, it will create an
    attribute for every $name in the list. The %options will be passed to
    the constructor for Moose::Meta::Attribute (which inherits from
    Class::MOP::Attribute), so the full documentation for the valid options
    can be found there. These are the most commonly used options:

    *is => 'rw'|'ro'*
        The *is* option accepts either *rw* (for read/write) or *ro* (for
        read only). These will create either a read/write accessor or a
        read-only accessor respectively, using the same name as the $name of
        the attribute.

        If you need more control over how your accessors are named, you can
        use the reader, writer and accessor options inherited from
        Class::MOP::Attribute, however if you use those, you won't need the
        *is* option.

    *isa => $type_name*
        The *isa* option uses Moose's type constraint facilities to set up
        runtime type checking for this attribute. Moose will perform the
        checks during class construction, and within any accessors. The
        $type_name argument must be a string. The string may be either a
        class name or a type defined using Moose's type definition features.
        (Refer to Moose::Util::TypeConstraints for information on how to
        define a new type, and how to retrieve type meta-data).

    *coerce => (1|0)*
        This will attempt to use coercion with the supplied type constraint
        to change the value passed into any accessors or constructors. You
        must supply a type constraint, and that type constraint must define
        a coercion. See Moose::Cookbook::Basics::HTTP_SubtypesAndCoercion
        for an example.

    *does => $role_name*
        This will accept the name of a role which the value stored in this
        attribute is expected to have consumed.

    *required => (1|0)*
        This marks the attribute as being required. This means a value must
        be supplied during class construction, *or* the attribute must be
        lazy and have either a default or a builder. Note that "required"
        does not say anything about the attribute's value, which can be
        "undef".

    *weak_ref => (1|0)*
        This will tell the class to store the value of this attribute as a
        weakened reference. If an attribute is a weakened reference, it
        cannot also be coerced. Note that when a weak ref expires, the
        attribute's value becomes undefined, and is still considered to be
        set for purposes of predicate, default, etc.

    *lazy => (1|0)*
        This will tell the class to not create this slot until absolutely
        necessary. If an attribute is marked as lazy it must have a default
        or builder supplied.

    *trigger => $code*
        The *trigger* option is a CODE reference which will be called after
        the value of the attribute is set. The CODE ref is passed the
        instance itself, the updated value, and the original value if the
        attribute was already set.

        You can have a trigger on a read-only attribute.

        NOTE: Triggers will only fire when you assign to the attribute,
        either in the constructor, or using the writer. Default and built
        values will not cause the trigger to be fired.

    *handles => ARRAY | HASH | REGEXP | ROLE | ROLETYPE | DUCKTYPE | CODE*
        The *handles* option provides Moose classes with automated
        delegation features. This is a pretty complex and powerful option.
        It accepts many different option formats, each with its own benefits
        and drawbacks.

        NOTE: The class being delegated to does not need to be a Moose based
        class, which is why this feature is especially useful when wrapping
        non-Moose classes.

        All *handles* option formats share the following traits:

        You cannot override a locally defined method with a delegated
        method; an exception will be thrown if you try. That is to say, if
        you define "foo" in your class, you cannot override it with a
        delegated "foo". This is almost never something you would want to
        do, and if it is, you should do it by hand and not use Moose.

        You cannot override any of the methods found in Moose::Object, or
        the "BUILD" and "DEMOLISH" methods. These will not throw an
        exception, but will silently move on to the next method in the list.
        My reasoning for this is that you would almost never want to do
        this, since it usually breaks your class. As with overriding locally
        defined methods, if you do want to do this, you should do it
        manually, not with Moose.

        You do not *need* to have a reader (or accessor) for the attribute
        in order to delegate to it. Moose will create a means of accessing
        the value for you, however this will be several times less efficient
        then if you had given the attribute a reader (or accessor) to use.

        Below is the documentation for each option format:

        "ARRAY"
            This is the most common usage for *handles*. You basically pass
            a list of method names to be delegated, and Moose will install a
            delegation method for each one.

        "HASH"
            This is the second most common usage for *handles*. Instead of a
            list of method names, you pass a HASH ref where each key is the
            method name you want installed locally, and its value is the
            name of the original method in the class being delegated to.

            This can be very useful for recursive classes like trees. Here
            is a quick example (soon to be expanded into a Moose::Cookbook
            recipe):

              package Tree;
              use Moose;

              has 'node' => (is => 'rw', isa => 'Any');

              has 'children' => (
                  is      => 'ro',
                  isa     => 'ArrayRef',
                  default => sub { [] }
              );

              has 'parent' => (
                  is          => 'rw',
                  isa         => 'Tree',
                  weak_ref    => 1,
                  handles     => {
                      parent_node => 'node',
                      siblings    => 'children',
                  }
              );

            In this example, the Tree package gets "parent_node" and
            "siblings" methods, which delegate to the "node" and "children"
            methods (respectively) of the Tree instance stored in the
            "parent" slot.

            You may also use an array reference to curry arguments to the
            original method.

              has 'thing' => (
                  ...
                  handles => { set_foo => [ set => 'foo' ] },
              );

              # $self->set_foo(...) calls $self->thing->set('foo', ...)

            The first element of the array reference is the original method
            name, and the rest is a list of curried arguments.

        "REGEXP"
            The regexp option works very similar to the ARRAY option, except
            that it builds the list of methods for you. It starts by
            collecting all possible methods of the class being delegated to,
            then filters that list using the regexp supplied here.

            NOTE: An *isa* option is required when using the regexp option
            format. This is so that we can determine (at compile time) the
            method list from the class. Without an *isa* this is just not
            possible.

        "ROLE" or "ROLETYPE"
            With the role option, you specify the name of a role or a role
            type whose "interface" then becomes the list of methods to
            handle. The "interface" can be defined as; the methods of the
            role and any required methods of the role. It should be noted
            that this does not include any method modifiers or generated
            attribute methods (which is consistent with role composition).

        "DUCKTYPE"
            With the duck type option, you pass a duck type object whose
            "interface" then becomes the list of methods to handle. The
            "interface" can be defined as the list of methods passed to
            "duck_type" to create a duck type object. For more information
            on "duck_type" please check Moose::Util::TypeConstraints.

        "CODE"
            This is the option to use when you really want to do something
            funky. You should only use it if you really know what you are
            doing, as it involves manual metaclass twiddling.

            This takes a code reference, which should expect two arguments.
            The first is the attribute meta-object this *handles* is
            attached to. The second is the metaclass of the class being
            delegated to. It expects you to return a hash (not a HASH ref)
            of the methods you want mapped.

    *traits => [ @role_names ]*
        This tells Moose to take the list of @role_names and apply them to
        the attribute meta-object. Custom attribute metaclass traits are
        useful for extending the capabilities of the *has* keyword: they are
        the simplest way to extend the MOP, but they are still a fairly
        advanced topic and too much to cover here.

        See "Metaclass and Trait Name Resolution" for details on how a trait
        name is resolved to a role name.

        Also see Moose::Cookbook::Meta::Labeled_AttributeTrait for a
        metaclass trait example.

    *builder* => Str
        The value of this key is the name of the method that will be called
        to obtain the value used to initialize the attribute. See the
        builder option docs in Class::MOP::Attribute and/or
        Moose::Cookbook::Basics::BinaryTree_BuilderAndLazyBuild for more
        information.

    *default* => SCALAR | CODE
        The value of this key is the default value which will initialize the
        attribute.

        NOTE: If the value is a simple scalar (string or number), then it
        can be just passed as is. However, if you wish to initialize it with
        a HASH or ARRAY ref, then you need to wrap that inside a CODE
        reference. See the default option docs in Class::MOP::Attribute for
        more information.

    *clearer* => Str
        Creates a method allowing you to clear the value. See the clearer
        option docs in Class::MOP::Attribute for more information.

    *predicate* => Str
        Creates a method to perform a basic test to see if a value has been
        set in the attribute. See the predicate option docs in
        Class::MOP::Attribute for more information.

        Note that the predicate will return true even for a "weak_ref"
        attribute whose value has expired.

    *documentation* => $string
        An arbitrary string that can be retrieved later by calling
        "$attr->documentation".

  has +$name => %options
    This is variation on the normal attribute creator "has" which allows you
    to clone and extend an attribute from a superclass or from a role. Here
    is an example of the superclass usage:

      package Foo;
      use Moose;

      has 'message' => (
          is      => 'rw',
          isa     => 'Str',
          default => 'Hello, I am a Foo'
      );

      package My::Foo;
      use Moose;

      extends 'Foo';

      has '+message' => (default => 'Hello I am My::Foo');

    What is happening here is that My::Foo is cloning the "message"
    attribute from its parent class Foo, retaining the "is => 'rw'" and "isa
    => 'Str'" characteristics, but changing the value in "default".

    Here is another example, but within the context of a role:

      package Foo::Role;
      use Moose::Role;

      has 'message' => (
          is      => 'rw',
          isa     => 'Str',
          default => 'Hello, I am a Foo'
      );

      package My::Foo;
      use Moose;

      with 'Foo::Role';

      has '+message' => (default => 'Hello I am My::Foo');

    In this case, we are basically taking the attribute which the role
    supplied and altering it within the bounds of this feature.

    Note that you can only extend an attribute from either a superclass or a
    role, you cannot extend an attribute in a role that composes over an
    attribute from another role.

    Aside from where the attributes come from (one from superclass, the
    other from a role), this feature works exactly the same. This feature is
    restricted somewhat, so as to try and force at least *some* sanity into
    it. Most options work the same, but there are some exceptions:

    *reader*
    *writer*
    *accessor*
    *clearer*
    *predicate*
        These options can be added, but cannot override a superclass
        definition.

    *traits*
        You are allowed to add additional traits to the "traits" definition.
        These traits will be composed into the attribute, but preexisting
        traits are not overridden, or removed.

  before $name|@names|\@names|qr/.../ => sub { ... }
  after $name|@names|\@names|qr/.../ => sub { ... }
  around $name|@names|\@names|qr/.../ => sub { ... }
    These three items are syntactic sugar for the before, after, and around
    method modifier features that Class::MOP provides. More information on
    these may be found in Moose::Manual::MethodModifiers and the
    Class::MOP::Class documentation.

  override ($name, &sub)
    An "override" method is a way of explicitly saying "I am overriding this
    method from my superclass". You can call "super" within this method, and
    it will work as expected. The same thing *can* be accomplished with a
    normal method call and the "SUPER::" pseudo-package; it is really your
    choice.

  super
    The keyword "super" is a no-op when called outside of an "override"
    method. In the context of an "override" method, it will call the next
    most appropriate superclass method with the same arguments as the
    original method.

  augment ($name, &sub)
    An "augment" method, is a way of explicitly saying "I am augmenting this
    method from my superclass". Once again, the details of how "inner" and
    "augment" work is best described in the
    Moose::Cookbook::Basics::Document_AugmentAndInner.

  inner
    The keyword "inner", much like "super", is a no-op outside of the
    context of an "augment" method. You can think of "inner" as being the
    inverse of "super"; the details of how "inner" and "augment" work is
    best described in the Moose::Cookbook::Basics::Document_AugmentAndInner.

  blessed
    This is the "Scalar::Util::blessed" function. It is highly recommended
    that this is used instead of "ref" anywhere you need to test for an
    object's class name.

  confess
    This is the "Carp::confess" function, and exported here for historical
    reasons.

METACLASS
    When you use Moose, you can specify traits which will be applied to your
    metaclass:

        use Moose -traits => 'My::Trait';

    This is very similar to the attribute traits feature. When you do this,
    your class's "meta" object will have the specified traits applied to it.

  Metaclass and Trait Name Resolution
    By default, when given a trait name, Moose simply tries to load a class
    of the same name. If such a class does not exist, it then looks for a
    class matching Moose::Meta::$type::Custom::Trait::$trait_name. The $type
    variable here will be one of Attribute or Class, depending on what the
    trait is being applied to.

    If a class with this long name exists, Moose checks to see if it has the
    method "register_implementation". This method is expected to return the
    *real* class name of the trait. If there is no "register_implementation"
    method, it will fall back to using
    Moose::Meta::$type::Custom::Trait::$trait as the trait name.

    The lookup method for metaclasses is the same, except that it looks for
    a class matching Moose::Meta::$type::Custom::$metaclass_name.

    If all this is confusing, take a look at
    Moose::Cookbook::Meta::Labeled_AttributeTrait, which demonstrates how to
    create an attribute trait.

UNIMPORTING FUNCTIONS
  unimport
    Moose offers a way to remove the keywords it exports, through the
    "unimport" method. You simply have to say "no Moose" at the bottom of
    your code for this to work. Here is an example:

        package Person;
        use Moose;

        has 'first_name' => (is => 'rw', isa => 'Str');
        has 'last_name'  => (is => 'rw', isa => 'Str');

        sub full_name {
            my $self = shift;
            $self->first_name . ' ' . $self->last_name
        }

        no Moose; # keywords are removed from the Person package

EXTENDING AND EMBEDDING MOOSE
    To learn more about extending Moose, we recommend checking out the
    "Extending" recipes in the Moose::Cookbook, starting with
    Moose::Cookbook::Extending::ExtensionOverview, which provides an
    overview of all the different ways you might extend Moose.
    Moose::Exporter and Moose::Util::MetaRole are the modules which provide
    the majority of the extension functionality, so reading their
    documentation should also be helpful.

  The MooseX:: namespace
    Generally if you're writing an extension *for* Moose itself you'll want
    to put your extension in the "MooseX::" namespace. This namespace is
    specifically for extensions that make Moose better or different in some
    fundamental way. It is traditionally not for a package that just happens
    to use Moose. This namespace follows from the examples of the "LWPx::"
    and "DBIx::" namespaces that perform the same function for "LWP" and
    "DBI" respectively.

METACLASS COMPATIBILITY AND MOOSE
    Metaclass compatibility is a thorny subject. You should start by reading
    the "About Metaclass compatibility" section in the Class::MOP docs.

    Moose will attempt to resolve a few cases of metaclass incompatibility
    when you set the superclasses for a class, in addition to the cases that
    Class::MOP handles.

    Moose tries to determine if the metaclasses only "differ by roles". This
    means that the parent and child's metaclass share a common ancestor in
    their respective hierarchies, and that the subclasses under the common
    ancestor are only different because of role applications. This case is
    actually fairly common when you mix and match various "MooseX::*"
    modules, many of which apply roles to the metaclass.

    If the parent and child do differ by roles, Moose replaces the metaclass
    in the child with a newly created metaclass. This metaclass is a
    subclass of the parent's metaclass which does all of the roles that the
    child's metaclass did before being replaced. Effectively, this means the
    new metaclass does all of the roles done by both the parent's and
    child's original metaclasses.

    Ultimately, this is all transparent to you except in the case of an
    unresolvable conflict.

CAVEATS
    It should be noted that "super" and "inner" cannot be used in the same
    method. However, they may be combined within the same class hierarchy;
    see t/basics/override_augment_inner_super.t for an example.

    The reason for this is that "super" is only valid within a method with
    the "override" modifier, and "inner" will never be valid within an
    "override" method. In fact, "augment" will skip over any "override"
    methods when searching for its appropriate "inner".

    This might seem like a restriction, but I am of the opinion that keeping
    these two features separate (yet interoperable) actually makes them easy
    to use, since their behavior is then easier to predict. Time will tell
    whether I am right or not (UPDATE: so far so good).

GETTING HELP
    We offer both a mailing list and a very active IRC channel.

    The mailing list is <mailto:moose AT perl.org>. You must be subscribed to
    send a message. To subscribe, send an empty message to
    <mailto:moose-subscribe AT perl.org>

    You can also visit us at "#moose" on <irc://irc.perl.org/#moose> This
    channel is quite active, and questions at all levels (on Moose-related
    topics ;) are welcome.

WHAT DOES MOOSE STAND FOR?
    Moose doesn't stand for one thing in particular, however, if you want,
    here are a few of our favorites. Feel free to contribute more!

    *   Make Other Object Systems Envious

    *   Makes Object Orientation So Easy

    *   Makes Object Orientation Spiffy- Er (sorry ingy)

    *   Most Other Object Systems Emasculate

    *   Moose Often Ovulate Sorta Early

    *   Moose Offers Often Super Extensions

    *   Meta Object Obligates Salivary Excitation

    *   Meta Object Orientation Syntax Extensions

ACKNOWLEDGEMENTS
    I blame Sam Vilain for introducing me to the insanity that is
    meta-models.
    I blame Audrey Tang for then encouraging my meta-model habit in #perl6.
    Without Yuval "nothingmuch" Kogman this module would not be possible,
    and it certainly wouldn't have this name ;P
    The basis of the TypeContraints module was Rob Kinyon's idea originally,
    I just ran with it.
    Thanks to mst & chansen and the whole #moose posse for all the early
    ideas/feature-requests/encouragement/bug-finding.
    Thanks to David "Theory" Wheeler for meta-discussions and spelling
    fixes.

  Books
    The Art of the MetaObject Protocol
        I mention this in the Class::MOP docs too, as this book was critical
        in the development of both modules and is highly recommended.

  Papers
    <http://www.cs.utah.edu/plt/publications/oopsla04-gff.pdf>
        This paper (suggested by lbr on #moose) was what lead to the
        implementation of the "super"/"override" and "inner"/"augment"
        features. If you really want to understand them, I suggest you read
        this.

BUGS
    All complex software has bugs lurking in it, and this module is no
    exception.

    Please report any bugs to "bug-moose AT rt.org", or through the web
    interface at <http://rt.cpan.org>. You can also submit a "TODO" test as
    a pull request at <https://github.com/moose/Moose>.

    You can also discuss feature requests or possible bugs on the Moose
    mailing list (moose AT perl.org) or on IRC at <irc://irc.perl.org/#moose>.

FEATURE REQUESTS
    We are very strict about what features we add to the Moose core,
    especially the user-visible features. Instead we have made sure that the
    underlying meta-system of Moose is as extensible as possible so that you
    can add your own features easily.

    That said, occasionally there is a feature needed in the meta-system to
    support your planned extension, in which case you should either email
    the mailing list (moose AT perl.org) or join us on IRC at
    <irc://irc.perl.org/#moose> to discuss. The Moose::Manual::Contributing
    has more detail about how and when you can contribute.

CABAL
    There are only a few people with the rights to release a new version of
    Moose. The Moose Cabal are the people to go to with questions regarding
    the wider purview of Moose. They help maintain not just the code but the
    community as well. See the list below under "AUTHORS".

CONTRIBUTORS
    Moose is a community project, and as such, involves the work of many,
    many members of the community beyond just the members in the cabal. In
    particular:
