111 | Moose::Meta::Role::Application - A base class for role application |
fb1e11d5 |
112 | |
113 | =head1 DESCRIPTION |
114 | |
115 | This is the abstract base class for role applications. |
116 | |
a5583b3a |
117 | The API for this class and its subclasses still needs some |
118 | consideration, and is intentionally not yet documented. |
