Adding new package for CPAN module Role::Tiny version 1.001004 into
devel/p5-Role-Tiny as requirement for upcoming update for devel/p5-Moo.
Role::Tiny is a minimalist role composition tool.
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 the class wins. If multiple
roles are applied in a single call (single with statement), then if any
of their provided methods clash, an exception is raised unless the class
provides a method since this conflict indicates a potential problem.
