#9633: PolyKinds in 7.8.2 vs 7.8.3 -------------------------------------+------------------------------------- Reporter: crockeea | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.3 Resolution: | Keywords: PolyKinds Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Unknown Type of failure: GHC | Blocked By: rejects valid program | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by crockeea): I verified that adding `TypeFamilies` to Foo.hs in 7.8.3 makes the original example compile fine. I'm happy with the error in HEAD, so it looks like this problem will not be an issue in 7.10. Thanks for investigating Simon! -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9633#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
