Re^3: How to Do Multiple OR in For Loops

I was wondering if the short circuit could cause side effects. But in this case there is no risk of auto-vivication.

With side-effects I'd rather prefer a non short circuit solution for clarity.

If a ~~short circuit effect is~~ side effects areš wanted, it should be done explicitly.

Cheers Rolf

If a short circuit effect is wanted, it should be done explicitly. That appears to be saying "if you want the short circuit effects of \|\| and &&, you shouldn't use \|\| and &&, but do it explicitly, but it's ok to use \|\| and && (and get the short circuiting) if you don't want it". But that would be strange, and it's probably not what you wanted to communicate. Personally, I very much prefer to write things like: `if (ref $code && $code->()) {...} # short circuit` [download] instead of `if (ref $code) { if ($code->()) { # explicitly ... } }` [download] It's a long time since I coded Pascal, and I don't miss much of it. Actually, I don't think I miss anything from it.	[reply] [d/l] [select]

I meant if side effects are wanted they shouldn't be limited to elements till short circuit. e.g. if you want auto-vivication do it for all of them. Corrected in the -2 post. Cheers Rolf	[reply]
