#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: | -------------------------------------+------------------------------------- Changes (by RyanGlScott): * related: #11228 => #11228, #11970 Comment: Oh bother. Just as I finished up a patch for this, I realized that at one point in time, GHC did exactly what was described in comment:5 by having a `Parent` constructor named `PatternSynonym`. However, `PatternSynonym` was deliberately removed in e660f4bf546e90fb6719ad268ca3daaecdce4b82 (#11970)! Looking at that commit, my patch essentially just adds all of that functionality back plus some changes to `isRecFldGRE`. I'm not sure how to proceed from here—I don't want to trample on other people's work! mpickering, you authored of that commit: do you have an opinion on this? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14630#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
