65 | =head1 NAME |
66 | |
67 | Moose::Meta::Method::Augmented - A Moose Method metaclass for augmented methods |
68 | |
69 | =head1 DESCRIPTION |
70 | |
71 | This class implements method augmenting logic for the L<Moose> C<augment> keyword. |
72 | |
73 | This involves setting up C<inner> for the superclass body, and dispatching to |
74 | the superclass from the normal body. |
75 | |
76 | The subclass definition (the augmentation itself) will be invoked explicitly |
77 | using the C<inner> keyword from the parent class's method definition. |

90 | exception. If you find a bug please either email me, or add the bug |
