I'm interested in why you find your preference "better".

The OP asked for something Perl-ish, so anything more Perl-ish than the C-ish code he provided is better in this context. Since C doesn't have the .. operator, this qualifies.

I also think it's more readable. Instead of having to deal with three expressions, three operators and a keyword inside for's parens, the solution I presented has one operator. The iterator's decleration is even sperated from the bounds for extra readability.

Yeah, because it's special cased. The C-style loop doesn't create a list at all, and is even "optimized" in older versions of Perl.

My point was that the performance isn't any worse than the C version, contrary to what I once thought, and contrary to what many probably think.
