Perl - OOP/Moose - method signatures

Question

I like to code OO in Perl like this:

use MooseX::Declare;
use Method::Signatures::Modifiers;
use v5.14.2;


class Talker
{
     method talk (Str $text) {
         $self=>say $text;

     }

     my $talk_object = Talker->new();
     $talk_object->talk('Hello!');
}

Unfortunately this is quite slow, I couldn't find any Mouse or Moo equivalent to it. What a pity that Perl hasn't got anything like PyPy.

Does someone know how to archive the same with the lighter implementations?

Answer 1

The experimental Moops module is another syntax extension that works fairly similar. It is inspired by MooseX::Declare (but is faster) and by the p5-mop project that is trying to bring such syntax into core perl.

Your example would translate without significant changes. If you want to specify a MOP backend, you can declare a class like class Foo using Moose, but it defaults to Moo, which is simpler than Moose.
