#14710: GHC 8.4.1-alpha allows the use of kind polymorphism without PolyKinds -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: closed Priority: high | Milestone: 8.6.1 Component: Compiler (Type | Version: 8.4.1-alpha1 checker) | Resolution: fixed | Keywords: PolyKinds Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: GHC accepts | Test Case: invalid program | polykinds/T14710 Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D4554 Wiki Page: | -------------------------------------+------------------------------------- Changes (by RyanGlScott): * testcase: => polykinds/T14710 * status: patch => closed * resolution: => fixed * milestone: 8.4.1 => 8.6.1 Comment: It's probably not wise to merge this into 8.4.2, since this technically causes `PolyKinds` to reject more programs than before (even if the programs it was erroneously accepting were only valid for a few GHC releases). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14710#comment:11 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
