caps1 s = all (\x -> isUpper (head x)) (words s) This seems fine, but you need to check that words never returns a list containing the empty string (otherwise `head' will fail).
Is there any such case? I was thinking about that as well, but couldn't think of any case where head would be called on an empty list. -- Deniz Dogan
