I've defined a function similar to
check x assoc = let found = lookup x assoc in when (isJust found) $ putStrLn $ "found " ++ fromJust found
which I've used several times from within the IO monad. Is there a more compact way of doing this?
maybe (return ()) (putStrLn . ("found " ++)) found is the best I could do.
