You could turn on -Wall to get a whole bunch of such warnings.

Hi, Today I found the following problem when writing a simple function:-- Whole info from a word8 list to moves movesFromWord8s :: [Word8] -> [Move] movesFromWord8s (f:t:ws) = (f, t) : movesFromWord8s ws moverFromWord8s _ = []Here I made a small typo in the second equation, writing "mover..." instead of "moves..." for the name of the declared function. Of course this is anerror, because I have non-exhaustive patterns in the functionmovesFromWord8s. But the compiler (here GHC 6.8.2 on WinXP) has in principleno chance to detect this mistake, I saw it only in QuickCheck (aka at run-time).I think this is a basic problem with the language design. In small programs it's not so bad, but in large ones this could be. What do you think aboutit? Are there possible solutions or workarounds?
