#14419: Check kinds for ambiguity -------------------------------------+------------------------------------- Reporter: goldfire | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.1 Resolution: | Keywords: TypeInType Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by RyanGlScott): After faec8d358985e5d0bf363bd96f23fe76c9e281f7, this is partially done. This data type's kind is currently rejected for being ambiguous: {{{#!hs type family F a data T1 :: forall a. F a -> Type }}} However, it would be premature to call this issue fixed, since the following two data types with very similar kinds are //not// rejected as ambiguous: {{{#!hs data T2 :: F a -> Type data T3 (b :: F a) }}} -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14419#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
