#9043: Add missing type class instances for data types in GHC.Generics -------------------------------------+------------------------------------ Reporter: ocharles | Owner: dreixel Type: feature request | Status: patch Priority: normal | Milestone: Component: libraries/base | Version: 7.8.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by ocharles): Alright, I've responded to some comments and added more instances. Could people please have another look? I wrote out Data instances, but I have never actually used Data.Data, so I may have got that wrong. Is it possible to write Data instances for (:+:) and friends? My initial attempt was no, but I may have missed something. Latest code is at https://github.com/ocharles/ghc/tree/generics-instances (as before). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9043#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
