42 | =head1 NAME |
43 | |
44 | Class::MOP::MiniTrait - Extremely limited trait application |
45 | |
46 | =head1 DESCRIPTION |
47 | |
48 | This package provides a single function, C<apply>, which does a half-assed job |
49 | of applying a trait to a class. It exists solely for use inside Class::MOP and |
50 | L<Moose> core classes. |
