Comment(by rl):

 Ideally yes, but Haskell doesn't really support that. The closest is the
 new GHC extension:

 {{{
 class Monad m => NFDataM m a where
   mrnf :: a -> m ()

   default mrnf :: NFData a => a -> m ()
   mrnf x = rnf x `seq` return ()
 }}}

 But you'd still have to say

 {{{
 instance NFDataM m MyType
 }}}
