Re^4: How to Do Multiple OR in For Loops

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.

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]
