So I don't see a problem "Problem" is too strong a word; I think "quibble" or "niggle" might do better. I was thinking that if someone said POSIX::lc() instead of the normal lc(), then they might be expecting it to always use the POSIX sense. I'm coming to think of POSIX compatibility more as a legacy matter than something genuinely useful in a Unicode world. I'd ask whether this is only for strings without the UTF-8 flag turned on them, but that would just display my ignorance of some of the hard work you've put in. I'll go read. --tomThread Previous | Thread Next
