I would write digitList :: Parser [Int] digitList = do l <- many digit let l' = map ( read -- read the string . (: []) -- convert the digit from a char to a string so I can "read" it ) l return l' That can be shortened to : digitList :: Parser [Int] digitList = map ( read.(:[])) `fmap` many digit David.
