"deriving Eq" i.e. following "data List a = List a" creates an instance like: instance Eq a => Eq (List a) where <compiler implementation> The problem was discussed for Stand-alone deriving declarations: http://www.haskell.org/ghc/docs/latest/html/users_guide/deriving.html Cheers Christian _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
