#8813: further support deriving instances Typeable1, Typeable2, etc ----------------------------------------------+---------------------------- Reporter: maeder | Owner: Type: task | Status: closed Priority: normal | Milestone: Component: Compiler | Version: Resolution: wontfix | 7.8.1-rc1 Operating System: Unknown/Multiple | Keywords: Type of failure: GHC rejects valid program | Architecture: Test Case: | Unknown/Multiple Blocking: | Difficulty: Unknown | Blocked By: | Related Tickets: ----------------------------------------------+---------------------------- Comment (by carter): @maeder, nope, please use CPP. CPP allows us to better support evolving / improving GHC while still ensuring that code can work across multiple GHC versions. Please use it. :) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8813#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
