# ABSTRACT: Method Meta Object for methods which implement overloading

__END__

=pod

=head1 DESCRIPTION

This is a L<Class::MOP::Method> subclass which represents methods that
implement overloading.

=head1 METHODS

=over 4

=item B<< Class::MOP::Method::Overload->wrap($metamethod, %options) >>

This is the constructor. The options accepted are identical to the ones
accepted by L<Class::MOP::Method>, except that it also required an C<operator>
parameter, which should be an operator as defined by the L<overload> pragma.

=item B<< $metamethod->operator >>

This returns the operator that was passed to new.
