I strongly disagree with this. There is a huge difference between f (x:xs) = ... and f (x:xs) = ... f [] = error "f: we expect a nonempty list" The reason for this is that in the second case you express to somebody who reads your code (including yourself) that this omission was intentional. The same holds for other warnings (although I sometimes am annoyed by the shadowing warnings, I agree :). My default is to start developing, then adding -Wall -Werror and make it compile again.
