Comment (by ryantrinkle):
I'm afraid it's my fault that these things have gotten mixed up. I asked
Dan to look into this stuff in the hope that it would give some benefit in
the Reflex case, but he found today that it doesn't quite fit. You're
absolutely right that the Writer case is still useful.
You're absolutely right about putting specialization under separate
tickets, and we'll be doing that if we find anything in that vein. In the
mean time, if Dan's work so far helps in the MonadWriter case, we'll try
to get that wrapped up for this ticket soon.
