#13391: PolyKinds is more permissive in GHC 8 -------------------------------------+------------------------------------- Reporter: crockeea | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.2 Resolution: | Keywords: newcomer, | TypeInType Operating System: Unknown/Multiple | Architecture: Type of failure: GHC accepts | Unknown/Multiple invalid program | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): I don't think this is quite so easy. The old check needed to tell the difference between types and kinds. We can't do that anymore! It is a shame that this happens though. If no one gets there first, I'll fix this in my `TypeInType` bug sweep this summer. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13391#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
