Comment(by rl):

 That's the question. Having the dependency (or a type function) probably
 makes more sense for things that actually live in monads. But as hvr
 points out, you might also want to have something like this:

 {{{
 instance NFDataM [a] m
 }}}

 That doesn't work with the dependency.

 Then there is also the question of what to do with monad transformers.
 This seems like a not entirely trivial design question, perhaps it's worth
 discussing on the libraries list.
