[Haskell-beginners] Warnings from ghc

Hi there, From my experiences in programming it is usually a good thing when a compiler issues warnings because this shows me where in my code there might be future problems hidden. I found the following warnings especially important to be turned on: -fwarn-incomplete-patterns -fwarn-overlapping-patterns -fwarn-name-shadowing -fwarn-unused-matches -fwarn-unused-do-bind I see that I could turn on all warnings with -Wall but that is a bit too much. My question: what other options do people recommend to be turned on. -- Manfred
