Easy enough to fix, but annoying to get good error messages in the mismatched associated type case (comment:2, which I think should be rejected). I'm afraid I think comment:3 is in error -- I don't understand what you're getting at. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14045#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
