(So I editted that comment after posting.) Note there's a `Eq a =>` constraint on the `GEq a a` instance; but not on the `GEq a b`. {{{ Dyn "hello" == Dyn "bye" ===> False Dyn "hello" == Dyn "hello" ===> True Dyn "hello" == Dyn 'b' ===> False }}} I agree @zaoqi's definition for `Dyn` is 'dodgy'. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14004#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
