I wonder if the implicit parameters extension could be useful for
helping in such a cleanup?

The idea is that we could have the granular ADTs as you suggest, but
pass them in via implicit parameters.  Code written like this seems
like it would be a little bit easier to modify: we just chuck another
implicit parameter in the type signature [although this may go a far
up the chain of calling functions]).

And we could avoid making yet another monad.  The extension seems
simple enough to understand anyway.  At least, I could understand it,
which is a good sign.
