Perl module for minimalist role composition
Role::Tiny is a Perl module to do minimalist role composition. Role composition can be thought of as much more clever and meaningful multiple inheritance.
The basics of this implementation of roles is:
* If a method is already defined on a class, that method will not be composed in from the role. * If a method that the role "requires" to be implemented is not implemented, role application will fail loudly.
Unlike Class::C3, where the last class inherited from "wins", role composition is the other way around, where first wins. In a more complete system (see Moose) roles are checked to see if they clash. The goal of this is to be much simpler, hence disallowing composition of multiple roles at once.
