Now lets consider using an algebraic datatype for regexps:

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 -- Best regards, Bulat mailto:bulatz@HotPOP.com
