Typed hole inside typed Template Haskell bracket causes panic
When I say:
m :: a -> a
m x = $$([||_||])I get:
T10946.hs:47:13:ghc: panic! (the 'impossible' happened)
(GHC version 7.10.1 for x86_64-unknown-linux):
No skolem info: a_apJ[sk]This happens both with GHC 7.10.1 and latest HEAD (e2b579e8).
