actualy native code compiler. Can't regex be done effectively in haskell ? Is it something that can't be done, or is it just such minimal effort to link to pcre that it's not worth the trouble ?
PCRE is pretty heavily optimized. POSIX regex engines generally rely on vendor regex libraries which my not be well optimized; there is a native Haskell implementation as well, but that one runs into a different issue, namely a lack of interest (regexes are often seen as "foreign" to Haskell-think, so there's little interest in making them work well; people who *do* need them for some reason usually punt to pcre).
