       Please report any bugs to <https://github.com/tobyink/p5-sub-handlesvia/issues>.

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

       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::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".

       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.

        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',
            },
          );
        }
