I tried to refactor RecSelId to RecSelId [DataCon] Bool but this causes some pain when it comes to the interface files. Next try it is something
#11031: Record Pattern Synonym Cleanup -------------------------------------+------------------------------------- Reporter: mpickering | Owner: Type: task | Status: new Priority: low | Milestone: Component: Compiler | Version: 7.10.2 Keywords: newcomer | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Ben comments that there are some loose ends with record pattern synonyms. * It's still not clear to me that the free variables produced in rnPatSynBind are correct * Perhaps in the future we want to refactor tc_single to use a function which extends the typechecking environment instead of using setGblEnv * @mpickering's suggested refactoring of RecSelId to RecSelId (Either PatSyn TyCon) Bool described in the comment in TcExpr.hs * There is a TODO in tc_patsyn_finish which should either be clarified so it can be considered actionable, removed, or just fixed The comment from TcExpr was: like RecSelId (Either PatSyn TyCon) Bool with the aim for something better in the future. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11031 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
