#13790: GHC doesn't reduce type family in kind signature unless its arm is twisted -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler (Type | Version: 8.2.1-rc2 checker) | Keywords: TypeInType, Resolution: | TypeFamilies Operating System: Unknown/Multiple | Architecture: Type of failure: GHC rejects | Unknown/Multiple valid program | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): Could this be a concrete example that tickles the problems discussed in #12088? Perhaps. Either that, or the fix for #11348 didn't go far enough. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13790#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
