Enable TypeHoles by default?

Mon Jan 13 12:30:32 UTC 2014

Maybe I'm missing something here, but how does specifying TypeHoles make GHC not compliant with Haskell 2010? Turning on TypeHoles should change only error messages. The set of programs that compile (and their meanings) should remain unchanged, by my understanding.

I'm mildly in favor of this change, but I agree that perhaps a conversation on the users list and/or waiting a cycle isn't a bad idea.
