in thread why does push not default to $_?

hmm. i think most people would write that usecase w/grep ...

push @even, grep { !($_%2) } 1 .. 100;

(i guess there could be other stuff going on in the loop, but then it's more likely that $_ would be named..

Actually I was thinking the same thing, when I wrote it! : )

As I said, it's just a *simple* usecase. But if you want to push to several arrays in the same loop, it may be handy!

Anyway it's not that I'm terribly missing one-parameter push, I just want to understand the underlying idea! And maybe be able to predict in which cases I can use default parameter without looking it up.
