#8263: allow duplicate deriving / standalone deriving -------------------------------------+------------------------------------ Reporter: aavogt | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 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 aavogt): Flag comes from cabal: that deriving (Typeable) was added in version 1.18. No code is needed to support that version. Things get messy to support older versions of Cabal which do not export a Typeable instance. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8263#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
