#9858: Typeable instances should be kind-aware -------------------------------------+------------------------------------- Reporter: dreixel | Owner: Type: bug | Status: new Priority: normal | Milestone: 7.12.1 Component: Compiler | Version: 7.9 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: Phab:D652 -------------------------------------+------------------------------------- Comment (by goldfire): You've hit smack into a blind spot of a dark corner of GHC's type system: `*` and `Constraint` are actually considered interchangeable in Core. So this failure isn't terribly surprising. But it's indeed a bug. I don't think it should be too hard to fix. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9858#comment:74 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
