Errgh. That may be true, but I did not consider non-monadic context at all, so I enforced this constrain mindlessly > It's a mater of taste which way to go, but I prefer importing modules > qualified rather than have type-suffixes on functions - so I would > rather use 'I.next' and 'A.next' instead of 'nextI' and 'nextA'.
