Kind Incompatibility in GHC 7.6.3

In this commit I have added a line with an intentionally missing dollar-sign. This should result in a mundane build failure, but instead, GHC produces this message:

src/Main.hs:50:3:
    Couldn't match kind `* -> *' with `*'
    Expected type: Window -> Maybe Integer -> t0 Curses (Maybe Event)
      Actual type: Window -> Maybe Integer -> t0 Curses (Maybe Event)
    Kind incompatibility when matching types:
      Window :: * -> *
      Window :: *
    The function `lift'ghc: panic! (the 'impossible' happened)
  (GHC version 7.6.3 for x86_64-unknown-linux):
        kindFunResult ghc-prim:GHC.Prim.*{(w) tc 34d}

Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug
