Perl 5 has a very similar concept (that is, start the message lookup=20
skipping the current namespace) that is also called "SUPER" but it's=20
written as a pseudo-class name:

=09package Whatever;
=09 at Whatever::ISA =3D ('BaseClass1', 'BaseClass2')
=09my $object =3D bless {}, 'Whatever';
        $object -> SUPER::someMethod();  # starts lookup in BaseClass1=20
rather than in Whatever.

--=20
