Re^4: why does push not default to $

Toolic, we perfectly know it's not implemented, we meditate WHY it's not implemented!

Here a simple usecase:

for (1 .. 100) {
 next if $_%2;
 push @even;
}

UPDATE...PS: Thanx for the interesting link to Builtin functions defaulting to $_

hmm. i think most people would write that usecase w/`grep` ... `push @even, grep { !($_%2) } 1 .. 100;` [download] (i guess there could be other stuff going on in the loop, but then it's more likely that `$_` would be named..	[reply] [d/l] [select]

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. Cheers Rolf	[reply]
