#7938: Unbound kind variable can appear in RHS of associated type -------------------------------------+------------------------------------- Reporter: goldfire | Owner: goldfire Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler | Version: 7.7 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: GHC accepts | Difficulty: Easy (less than 1 invalid program | hour) Test Case: indexed- | Blocked By: types/should_fail/T7938 | Related Tickets: Blocking: | -------------------------------------+------------------------------------- Changes (by goldfire): * status: new => closed * testcase: => indexed-types/should_fail/T7938 * resolution: => fixed Comment: Ack. I got caught in the same misunderstanding about return kinds as documented in #7939. The original file in the description of this bug should not compile, and it now doesn't. The modification I made in my previous comment (to add a `:: k`) to the declaration for `Bar` really ''should'' compile. I've added a test case for the original bug, but otherwise, no changes necessary. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/7938#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
