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.
