    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.
