=head1 NAME
Class::C3::next - Pure-perl next::method and friends
=head1 DESCRIPTION
This module is used internally by L<Class::C3> when
necessary, and shouldn't be used (or required in
distribution dependencies) directly. It
defines C<next::method>, C<next::can>, and
C<maybe::next::method> in pure perl.
