I'm aware that this is special case for those core functions operating on arrays. So, it's not so hard to track it at all, I think.
Actually, I don't understand why we need such syntax simplifications it they're not done through all the Perl. Changing Perl philosophy in one place, and not changing it in another is inconsistent and wrong. For example, we still don't have saner defaults for simple object-oriented programming although it is relatively simple to patch the core as demonstrated before on p5p.
