NAME

       Sub::HandlesVia::Declare - declare delegations at compile-time

SYNOPSIS

        use Sub::HandlesVia::Declare( $attr, $via => %delegations );

       This is roughly equivalent to the following:

        use Sub::HandlesVia qw(delegations);

        BEGIN {
          delegations(
            attribute    => $attr,
            handles_via  => $via,
            handles      => \%delegations,
          );
        };

       Except it doesn't import the "delegations" function into your namespace.

DESCRIPTION

       Useful for Object::Pad and kind of nice for Class::Tiny. Basically any class builder than
       does its stuff at compile time.

   Object::Pad
        use Object::Pad;

        class Kitchen {
          has @foods;
          use Sub::HandlesVia::Declare '@foods', Array => (
            all_foods => 'all',
            add_food  => 'push',
          );
        }

       If an attribute begins with a '@' or '%', $via can be omitted.

        use Object::Pad;

        class Kitchen {
          has @foods;
          use Sub::HandlesVia::Declare '@foods', (
            all_foods => 'all',
            add_food  => 'push',
          );
        }

   Class::Tiny
        package Kitchen;
        use Class::Tiny {
          foods  => sub { [] },
          drinks => sub { [ 'water' ] },
        };
        use Sub::HandlesVia::Declare 'foods', Array => (
          all_foods  => 'all',
          add_food   => 'push',
        );
        use Sub::HandlesVia::Declare 'drinks', Array => (
          all_drinks => 'all',
          add_drink  => 'push',
        );
