WARNING: this is ALPHA code. More features to be added later. {
When} using Moose::Role, a class which provides a method a role provides will silently override that method. This can cause strange, hard-to-debug errors when the role's methods are not called. Simple use MooseX::Role::Strict instead of Moose::Role and overriding a role's method becomes a composition-time failure.
