    [Type::Tiny::Manual::Policies] - [Type::Tiny] policies

## MANUAL
  [Type::Tiny] Stability Policy
    [Type::Tiny] 1.000000 is considered stable. Any changes to the API that
    are big enough to *require* changes to the test suite will be preceded
    by a *six month* notice period, with the following exceptions:

    *   Any changes which are necessary to maintain compatibility with new
        releases of Moose, Moo, and other software that [Type::Tiny] needs to
        integrate with.

    *   Changes to maintain compatibility with future versions of Perl
        itself.

    *   Where a change fixes a contradiction between the implementation and
        documentation of [Type::Tiny].

    *   Where a feature is explicitly documented as being "experimental" or
        "unstable".

    *   Improvements to the text of error messages.

  Experimental and Unstable [Type::Tiny] Features
    The following list is currently non-exhaustive.

    *   The following type checks result may vary based on your version of
        Perl and whether [Type::Tiny::XS] is installed. Their outcome is
        currently considered undefined, and may change in future versions.

        *   Using Object and similar type checks on unblessed regular
            expression references, the outcome is undefined.

        *   On all current versions of Perl, false ("!!0") stringifies to
            the empty string (but using [Devel::Peek] you can tell the
            difference between this value and a normal empty string), so Int
            and subtypes of Int do not consider it to be an integer. If
            Perl's behaviour ever changes, you might not be able to rely on
            this outcome. True ("!!1") stringifies as "1", so is considered
            an integer.

        *   A glob (not a globref but an actual glob) currently passes the
            StringLike type constraint but not the Str type constraint.

    *   [Type::Tiny]'s "my_methods" attribute and the functionality it
        provides is experimental.

    *   The parameterizable coercion API is subject to change.

    *   The interaction of deep coercions and mutable coercions currently
        results in ill-defined behaviour. This could change at any time.

    *   [Type::Registry]'s ability to import [MooseX::Types] and [MouseX::Types]
        type libraries is experimental.

    *   These modules are considered part of [Type::Tiny]'s internals, and not
        covered by the stability policy: [Devel::TypeTiny::Perl56Compat],
        [Devel::TypeTiny::Perl58Compat], [Type::Coercion::FromMoose],
        [Type::Tiny::_HalfOp], [Types::Standard::ArrayRef],
        [Types::Standard::CycleTuple], [Types::Standard::Dict],
        [Types::Standard::HashRef], [Types::Standard::Map],
        [Types::Standard::ScalarRef], [Types::Standard::StrMatch],
        [Types::Standard::Tied], and [Types::Standard::Tuple].

    *   [Reply::Plugin::TypeTiny] is not covered by the stability policy.

  [Type::Tiny] Versioning Policy
    As of 1.000000, this distribution follows a versioning scheme similar to
    Moo, which is based on a semver <<http://semver.org/>>-like three
    component version number, but with the last two components each
    represented by three decimal digits in the fractional part of the
    version number. That is, version 1.003002 of the software represents
    "1.3.2".

    Additionally, releases where the second component is an odd number will
    be considered unstable/trial releases. (These will also include an
    underscore in the version number as per the usual CPAN convention.)
