Re: Re: Perl style question: loops with postcondition

I don't like Nr.3 because I learned that goto: "It scans outward from your current location for the indicated label." (by larry wall) which decreases performance and just look weird (remembers me on basic and dos-batches...) to me...

I'll give you the basic and dos parts, but I'm fairly sure that "scans outward" would only apply if you're using the goto EXPR form, rather than a goto LABEL where the label is explicit.

For the goto LABEL form, the location of LABEL has to be resolved at compile time, so it's probably not very costly.
