GHC Panic when using unbound type variables created with newName in Template Haskell
I received the following GHC panic report: ghc: panic! (the 'impossible' happened)
(GHC version 7.4.1 for x86_64-apple-darwin):
nameModule n_a2kf{tv}
I was trying to generate the declaration of a GADT using Template Haskell when it happened.
