#15855: Warn about incomplete NamedFieldPuns patterns -------------------------------------+------------------------------------- Reporter: Artyom.Kazak | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.6.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): Can you be more precise about what you are asking for? I think it might be something like: * Warn about any record pattern that does not provide a pattern for every field of the record. What about {{{ g R{a,b} = a g R(a, ..} = a }}} Do those warn? Once we have a precise spec, I don't think this will be hard to implement (in the renamer). I can offer advice. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15855#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
