Turn on those compiler warnings! :)

-Wall yes, but -Wextra can get pretty obnoxious. In my experience, that one tends to flood you with "unused parameter" warnings every time you have an IBAction that doesn't use the "sender" parameter, or you have a notification handler that doesn't use the notification object, or you implement some API that requires you to implement certain functions or methods that contain parameters you don't need, etc.
