74862722 58Moose::Meta::Method::Overridden - A Moose Method metaclass for overridden methods
39b3bc94 59
60=head1 DESCRIPTION
61
18c2ec0e 62This class implements method overriding logic for the L<Moose> C<override> keyword.
63
64This involves setting up C<super> for the overriding body, and dispatching to
65the correct parent method upon its invocation.
