As I noted [https://ghc.haskell.org/trac/ghc/ticket/11135#comment:25 here], I plan to eventually create a language extension for deriving `Eq1` and friends, which will make adding these kinds of instances much less painful in the future. But we don't derive `Eq`, `Ord`, etc. for `Proxy` anyway to make the instances sufficiently lazy, so we should provide similar treatment for `Eq1`, `Ord1`, etc. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11756#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
