| Summary : Use Perl 6 roles in Perl 5
|
Description :
Class::Roles provides a Perl 5 implementation of Perl 6 roles.
Roles are named collections of reusable behavior. They provide a mechanism
to mark that a class performs certain behaviors and to reuse the code that
performs those behaviors.
Polymorphism is a fundamental feature of object orientation. It\'s important
that behaviors that are similar in a semantic sense but different in
specific details can be abstracted behind the same name. A dog may sleep by
turning in circles three times then lying down while a cat may sprawl out
across the nearest human lap. Both sleep, however.
Allomorphism -- polymorphic equivalence -- is a lesser-known feature. This
suggests that objects with compatible behavior should be able to be treated
interchangeably. A \'Dog\' and a \'Lifeguard\' may both understand the
\'rescue_drowning_swimmer\' message, not because they share a common ancestor
class but because they share a role.
