Jarkko was suggesting roll our own strtol (etc) for perl6. I was only thinking in terms of roll our own routine in 5.7 for sv_2[iun]v to call. And sv_2[iun]v only calls strtod if looks_like_number thinks that something looks like its idea of a number, which for integers is /^\s*[-+]?[0-9]+\s*$/ (if I have my regexp correct, but the important bit is no commas, (and hardcoded '0' to '9' instead of \d (and a fanatical loyalty to the Pope)) So I think that this means that sv_2[iun]v don't currently "do" locales. So roll-ones-own just for them doesn't need to either. but I think wait until HP UX and Irix are happy before doing more. Nicholas ClarkThread Previous | Thread Next
