Incorrect. It will not be compiled on every iteration, but its string form will be compared with its previous string form, to see whether it needs recompiling.

    I remember reading that it still did the recompile even if the variable in the regex did not change. Of course I read that a LONG time ago. Apparently it has been fixed.(probably a long time ago) So would the /o faster by avoiding the extra string compare? I know this would probably be insignificant unless there where a bajillion iterations. But I was just curious.
    Do you even know anything about regexes? (see sig)
