#9103: hackage's type-level-0.2.4 fails to compile -------------------------------------+------------------------------------- Reporter: slyfox | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler (Type | Version: 7.8.2 checker) | Keywords: Resolution: | Architecture: Operating System: Unknown/Multiple | Unknown/Multiple Type of failure: GHC rejects | Test Case: valid program | Blocking: Blocked By: | Differential Revisions: Related Tickets: #8634 | -------------------------------------+------------------------------------- Comment (by goldfire): My guess is that !PolyKinds is causing trouble in the not-promoted case. Do you have !PolyKinds enabled? Try running with `-fprint-explicit-kinds`. But, the "redundant constraint" warning is almost certainly wrong. I would post that as a separate bug, which we should try to fix by 7.10, I think. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9103#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
