SUPER is good, as btrott points out. You can also get more control, if you need it.

$o = Foo::Bar::Baz->new();
$o->blat($x);            # Foo::Bar::Baz::blat?
$o->SUPER::blat($x);     # Foo::Bar::blat?
Foo::Bar::blat($o, $x);
Foo::blat($o, $x);

This makes your code more dependent on the exact inheritance details of Foo::Bar::Baz, which is not a good thing if someone decides to change things around a little bit. If you find yourself doing this, take a step back and ask yourself if there is a better way.
