Re^14: RFC: OO Perl using Moo/Moose book (GoF / Updated)

So, the Perl Moo* equivalent would be something like

package My::Obj;
use Moo;
has deputy => (is => 'ro', delegates => 'frobnicate');
[download]

where calling $obj->frobnicate(42); would in fact call

$obj->deputy->can('frobnicate')->($obj, 42);
[download]

map{substr$_->[0],$_->[1]||0,1}[\*||{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^*ARGV,3]

Yes, looks like the WP definition of "Delegation" to me. But I'd say this niche is more or less (?)* filled by "Roles" in Moo/Moose ( of course with different implementation) Theoretically speaking. ..

As a side note, if you replace "deputy" with "__prototype__" and don't restrict to methods like "frobnicate" you'll have more or less the JS model of inheritance. That's why Self and JS are listed as examples for "Delegation".
