For people interested, here's the ticket. http://hackage.haskell.org/trac/ghc/ticket/3085 <http://hackage.haskell.org/trac/ghc/ticket/3085> Martijn Van Steenbergen indirectly revealed a feature request to the feature request feature of the feature database :-) Okay, I'll stop the nonsense: it would be nice if the community could rate the popularity of a feature request, which Martijn now just did by adding a comment.

I go back every so often and try removing each of the extensions listed in my LANGUAGE pragma. Didn't occur to me that the compiler could be doing it for me.

So you mean something like if you put {-# LANGUAGE GeneralizedNewtypeDeriving #-} in a file, but never do newtype deriving, it would warn you? I have no idea how hard that'd be to implement, but that sounds kind of cool. Useful for both refactoring and when you've inherited old code.
