Since I have very little experience with Haskell and am not used to Haskell-think yet, I don't quite understand your statement that regexes are seen as foreign to Haskell-think. Could you elaborate? What would a more "native" solution look like? From what I have learned so far, it seems to me that Haskell is a lot about clear, concise, and well structured code. I find regexes extremely compact and powerful, allowing for very concise code, which should fit the bill perfectly, or shouldn't it?

Thanks,

nick

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).
