I think this is quite cool. (Parsing an IRC 'NICK foo' message)

special = oneOf "-[]\\`^{}_" -- Taken from RFC1459, except '_', 

                             -- which I added (generally accepted character (are there others?)).



nick = do { string "NICK"; space;

            first <- letter; rest <- many1 $ alphaNum <|> special; eof;

            return $ Nick (first:rest) }

Not quite sure what I think of it in comparison to regular expressions, yet.
