#11811: GHC sometimes misses a CUSK -------------------------------------+------------------------------------- Reporter: goldfire | Owner: goldfire Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- {{{ {-# LANGUAGE TypeInType #-} data Test (a :: x) (b :: x) :: x -> * where K :: Test Int Bool Double }}} fails, because GHC thinks that `Test` does not have a CUSK. It should have a CUSK, because while there is no `forall x` in the result kind, the `x` is in scope from previous use in kinds. Fix en route. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11811 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

If there's a merge problem, I can probably work around it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11811#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
