When digging into #561, I noticed that in the program

data Fix f a = Fix (f (Fix f a))

instance Functor f => Functor (Fix f) where
  fmap f (Fix x) = _

the Functor f given isn't available inside of the hole. I guess the thetatype stuff only works for top-level defs.

This particular bug is fixed by #1517, but the example still doesn't work due to #1518. What a can of worms!
