Re^2: foreach funny business

Running your #2 on my perl does not die, and mine claims to be 5.8.8. Are you sure you're on your rocker? :-)

Anyway, to my way of thinking the shift() shouldn't be giving you anything other than _exactly_ what was in $_[0], not some copy.

Now who's with me? /me hoists pitchfork and torch

I'm with you, you're right, I'm not. And then, again you're right - 5.8.8 doesn't die, I copied from the wrong shell, and shift() should just pass $_[0], not a copy, unless somebody made `shift` ro-aware. Have to look after this... Mhm. Scanning perldelta... nothing. Then, it's a bug. Or it's just undefined behaviour? But hey, it's a clever one. It's like, say, putting your hand in the band-saw, and get a finger cut, but then you draw out your hand and it's ok because it's read-only. One finger extra ;-) --shmem _($_=" "x(1<<5)."?\n".q·/)Oo.
