NAME
    Specio::Constraint::AnyCan - A class for constraints which require a class name or object with a
    set of methods

VERSION
    version 0.47

SYNOPSIS
        my $type = Specio::Constraint::AnyCan->new(...);
        print $_, "\n" for @{ $type->methods };

DESCRIPTION
    This is a specialized type constraint class for types which require a class name or object with
    a defined set of methods.

API
    This class provides all of the same methods as Specio::Constraint::Simple, with a few
    differences:

  Specio::Constraint::AnyCan->new( ... )
    The "parent" parameter is ignored if it passed, as it is always set to the "Defined" type.

    The "inline_generator" and "constraint" parameters are also ignored. This class provides its own
    default inline generator subroutine reference.

    This class overrides the "message_generator" default if none is provided.

    Finally, this class requires an additional parameter, "methods". This must be an array reference
    of method names which the constraint requires. You can also pass a single string and it will be
    converted to an array reference internally.

  $any_can->methods
    Returns an array reference containing the methods this constraint requires.

ROLES
    This class does the Specio::Constraint::Role::IsaType, Specio::Constraint::Role::Interface, and
    Specio::Role::Inlinable roles.
