Kind operators not parsed

Take the following module:

{-# LANGUAGE DataKinds, TypeOperators, TypeFamilies #-}

data a + b = Inl a | Inr b

type family Foo :: Bool + Bool

HEAD produces

/Users/rae/temp/Bug.hs:5:25: parse error on input ‛+’

It seems that type operators promoted to kinds are not parsed correctly.
