If I remember correctly, interfaces in Java are a hack to get around
the fact that you can't do multiple inheritance. Perl can do multiple
inheritance*, so all you need to do is create a new class SomeName and
have other class inherites from it (the base pragma is the easiest
way).
* whether this is a good or bad thing depends on how likely you are to
run into diamond inheritance, and the other problems multiple
inheritance can cause.
