Not yet. It's still a few items down in the queue.

Enough desugaring to make Haskell "simple" (yes, I know that's subjective).
Probably somewhere around System-F (Fw perhaps, once I learn what that is).
The main things I can think of are getting rid of special notation (do,
list comp., where clauses, infix operators) and expanding typeclasses to

I haven't looked into it, but my guess is not. The main requirement is that
it (and its desugared target) needs to be really pure (no IO, FFI, or
polymorphic seq), and that it must be able to desugar itself. It might
provide a good launching point though.
