#13295: Failure to resolve type parameter determined by type family -------------------------------------+------------------------------------- Reporter: alexvieth | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler (Type | Version: 8.0.1 checker) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: GHC rejects | Unknown/Multiple valid program | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by alexvieth): I see. So the necessary theoretical work just hasn't been done. I hope that eventually `introG` can be accepted, but in the mean-time, perhaps we could come up with a more helpful error message? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13295#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
