[Haskell-cafe] use of -Werror

Is there a consensus within the Haskell community on the use of -Werror in packages uploaded to Cabal? Most places where I've worked, building with -Werror has been considered a laudable ideal, but fixing all the old warnings in the codebase was too much work, so it wasn't done. I suppose -Werror could cause problems in heterogeneous build environments. -- Johan Larson -- Toronto, Canada
