Comment(by rotsor): I've been able to also reproduce it without type classes: {{{ {-# LANGUAGE TypeFamilies #-} module M where type T v = Int type family TF a :: * type instance TF (T a) = a panic :: TF Int panic = undefined }}} -- Ticket URL: <http://hackage.haskell.org/trac/ghc/ticket/7536#comment:1> GHC <http://www.haskell.org/ghc/> The Glasgow Haskell Compiler _______________________________________________ Glasgow-haskell-bugs mailing list Glasgow-haskell-bugs@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-bugs
