Using Moose provides many immediate and obvious benefits, starting with the
obviation of typing "use strict" and "use warnings" in your classes.
The real power of Moose, however, rests in its extensibility. By subclassing
Moose's metaclasses, you can augment and change Moose's behavior to suit your
application's needs. This extensibility is powered by the meta-object protocol
of Moose's foundation, Class::MOP.
The motivating example for extending Moose will be the creation of a small web
framework to empower a Twitter-alike. The focus will be creating meta-level
roles so that metaclasses may select exactly which changes in behavior they
wish to exhibit. Modules that will be used include Moose::Exporter (to define
sugary keywords) and Moose::Util::MetaRole (to extend classes composably).
Experience with using Moose to create regular classes is expected. Having some
familiarity with roles will let you get more out of the talk. No experience
with metaprogramming is required.
