generalized newtype deriving not working with polymorphic component
I’d like generalized newtype deriving to work also with polymorphic components like in this example:
{-# LANGUAGE GeneralizedNewtypeDeriving, RankNTypes #-}
import Control.Monad.Cont
newtype PolyContT monad o = PolyContT (forall result. ContT result monad o)
deriving (Monad)
Would this be possible?
