#13555: Typechecker regression when combining PolyKinds and MonoLocalBinds -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: new Priority: highest | Milestone: 8.2.1 Component: Compiler (Type | Version: 8.1 checker) | Resolution: | Keywords: TypeInType 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 RyanGlScott): Ah, I suppose you mean in the instance signature: {{{#!hs instance CRTrans Maybe (GF fp d) where crtInfo :: forall (m :: k) . (Reflects m Int) => TaggedT m Maybe (CRTInfo (GF fp d)) crtInfo = undefined }}} i.e., changing `forall m` to `forall (m :: k)`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13555#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
