NAME

       Sub::HandlesVia - alternative handles_via implementation

SYNOPSIS

        package Kitchen {
          use Moo;
          use Sub::HandlesVia;
          use Types::Standard qw( ArrayRef Str );

          has food => (
            is          => 'ro',
            isa         => ArrayRef[Str],
            handles_via => 'Array',
            default     => sub { [] },
            handles     => {
              'add_food'    => 'push',
              'find_food'   => 'grep',
            },
          );
        }

        my $kitchen = Kitchen->new;
        $kitchen->add_food('Bacon');
        $kitchen->add_food('Eggs');
        $kitchen->add_food('Sausages');
        $kitchen->add_food('Beans');

        my @foods = $kitchen->find_food(sub { /^B/i });

DESCRIPTION

       If you've used Moose's native attribute traits, or MooX::HandlesVia before, you should
       have a fairly good idea what this does.

       Why re-invent the wheel? Well, this is an implementation that should work okay with Moo,
       Moose, Mouse, and any other OO toolkit you throw at it.  One ring to rule them all, so to
       speak.

       For details of how to use it, see the manual.

       Sub::HandlesVia::Manual::WithMoo
           How to use Sub::HandlesVia with Moo and Moo::Role.

       Sub::HandlesVia::Manual::WithMoose
           How to use Sub::HandlesVia with Moose and Moose::Role.

       Sub::HandlesVia::Manual::WithMouse
           How to use Sub::HandlesVia with Mouse and Mouse::Role.

       Sub::HandlesVia::Manual::WithMite
           How to use Sub::HandlesVia with Mite.

       Sub::HandlesVia::Manual::WithClassTiny
           How to use Sub::HandlesVia with Class::Tiny.

       Sub::HandlesVia::Manual::WithObjectPad
           How to use Sub::HandlesVia with Object::Pad classes.

       Sub::HandlesVia::Manual::WithGeneric
           How to use Sub::HandlesVia with other OO toolkits, and hand-written Perl classes.

       Note: as Sub::HandlesVia needs to detect which toolkit you are using, and often needs to
       detect whether your package is a class or a role, it needs to be loaded after
       Moo/Moose/Mouse/etc. Your "use Moo" or "use Moose::Role" or whatever needs to be before
       your "use Sub::HandlesVia".

       (There are known bugs for Moose native types that do coercion.)

       MouseX::NativeTraits, and MooX::HandlesVia with Data::Perl.

       Sub::HandlesVia::Declare is a helper for declaring Sub::HandlesVia delegations at compile-
       time, useful for Object::Pad and (to a lesser extent) Class::Tiny.
