#14042: Data type with type family in return kind spuriously rejected -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler (Type | Version: 8.0.1 checker) | Keywords: TypeInType, Resolution: | TypeFamilies 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 RyanGlScott): Fair enough, I can accept GHC rejecting occurrences of type families in data type return kinds. But at the very least the error message ought to be changed here, because the current one misleads readers from the real problem. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14042#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
