in reply to RFC: Should join subsume reduce?
As all the others seem to think this is a bad idea, I will voice my opinion that I think it is a good idea. It does not break existing code. It is similar enough that to me it seems logical that join should support more complex operations than only the simplest case. And finally i think that it would be great to have such functionality in base perl without installing yet another module.
