64
65Moose::Meta::Method::Augmented - A Moose Method metaclass for augmented methods
66
67=head1 DESCRIPTION
68
69This class implements method augmenting logic for the L<Moose> C<augment> keyword.
70
71This involves setting up C<inner> for the superclass body, and dispatching to
72the superclass from the normal body.
73
74The subclass definition (the augmentation itself) will be invoked explicitly
75using the C<inner> keyword from the parent class's method definition.
