#10598: DeriveAnyClass and GND don't work well together -------------------------------------+------------------------------------- Reporter: osa1 | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.11 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by osa1): @rwbarton, sorry if I'm misunderstand things, but I think `DeriveAnyClass` isn't deriving `Functor` because of an implementation bug and not because how it's designed. I think we should reconsider design of `DeriveAnyClass` and make the documentation more clear about it. As usual, I'm willing to work on this :) FWIW, I have a patch that fixes(based on my understanding of `DervieAnyClass`) some specific cases but without specifying it better it's pointless. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10598#comment:17 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
