btw, a year ago i written RE processing library, which used Parsec
both to parse and compile regexpr itself and to parse input string according to
compiled regexpr. i think, this have no practical meaning, but may be
included in parsec library as intersting example of its usage :)
unluckily, i dont debugged it and so don't send it to parsec author
