#14630: name shadowing warnings by record pattern synonyms + RecordWildCards or NamedFieldPuns -------------------------------------+------------------------------------- Reporter: mizunashi_mana | Owner: (none) Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.2.2 Resolution: | Keywords: | PatternSynonyms Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect | Unknown/Multiple error/warning at compile-time | Test Case: Blocked By: | Blocking: Related Tickets: #11228, #11970 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by RyanGlScott): mpickering, my patch is located here: https://github.com/RyanGlScott/ghc/commit/e1262b33092e8b3e2d8bfed588334d14aa... . The main highlights are that it adds a new constructor to `AvailInfo` and `Parent` corresponding to pattern synonym record fields. As I discovered, this is remarkably close to what the state of affairs was pre-#11970 (although back then the information tracked whether a name was a pattern synonym, not necessarily a pattern synonym record field, so perhaps I'm comparing apples to oranges). I'd certainly be open to a simpler approach, although it's not entirely clear to me at the moment what that would be. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14630#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
