=head1 NAME
Class::MOP::Method - Method Meta Object
=head1 SYNOPSIS
# ... more to come later maybe
=head1 DESCRIPTION
The Method Protocol is very small, since methods in Perl 5 are just
subroutines within the particular package. We provide a very basic
introspection interface.
=head1 METHODS
=head2 Introspection
=over 4
=item B<meta>
This will return a B<Class::MOP::Class> instance which is related
to this class.
