Plan B]. I only suggest Plan B to reduce the constraint sets by specialising them. If it doesn't affect the performance, I agree that the alternatives with less code is preferred. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14490#comment:4 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
