#13018: TH-spliced pattern synonym declaration fails to typecheck -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler (Type | Version: 8.0.1 checker) | Keywords: Resolution: | PatternSynonyms 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): Agreed that the splitting rule must be implemented in the TH quoting mechanism. Check out `RnTypes.extractHsTyRdrTyVars` and friends. If you have `HsType Name` (instead of `HsType RdrName`), you may be able to generalize these functions. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13018#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
