Need Help??

I thought that for (split //, $string) { would cost a lot of memory if $string is long, but now I'm not sure.

It will cost a lot of memory. Fortunately, `$string` is rarely large. And if it is large, the regex-iterator solution will probably be slow. You'll probably be better off with a `substr` solution on large strings. ---- I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident. -- Schemer `: () { :\|:& };:` Note: All code is untested, unless otherwise stated	[reply] [d/l] [select]

see Re: foreach (each character in string..)? which shows that substr is really the fastest.	[reply]
