Moose is a postmodern object system for Perl 5 that takes the tedium out of writing object-oriented Perl. It borrows all the best features from Perl 6, CLOS (Lisp), Smalltalk, Java, BETA, OCaml, Ruby and more, while still keeping true to its Perl 5 roots.

Moose is an extension of the Perl 5 object system. The main goal of Moose is to make Perl 5 object-oriented programming (OOP) easier, more consistent and less tedious. With Moose you can think more about what you want to do and less about the mechanics of OOP.

In Moose, how do I modify an attribute any time it is set?

If you have an attribute that needs to be modified any time it is set, is there a slick way of doing this short of writing the accessor yourself and mucking around directly with the content of $self, as done in this example? package Foo; use…

Is checking Perl function arguments worth it?

There's a lot of buzz about MooseX::Method::Signatures and even before that, modules such as Params::Validate that are designed to type check every argument to methods or functions. I'm considering using the former for all my future Perl code, both…

Resources for getting started on "modern" Perl

Moose "builder" vs "default"

I understand that using builder enables subclasses to override attribute defaults easily and roles can require them. This can also be accomplished using default like so: has 'foo' => is => 'rw', isa => 'Str', default => sub…
