But it is possible to give a construction of an Ord dictionary from an AssociatedMonad dictionary. See the attached code. It works like a charm. :-)
This is really cool, and with much wider applicability than restricted monads; it gives us a general way to abstract over type class constraints.
The NewMonad class is also very straightforward and I think will cause much fewer type-checking headaches and large type signatures than Oleg's solution.
