I think you're right. I dont know anywhere near enough to make any
kind of sensible changes to the middle end, but I can grok the front
end stuff OK. I already have it working for C, and I will look at
doing it for C++ next. Those are my two big concerns. If I end up
having to do this in all of the frontends (well, its just Fortran
and Java after that for this platform) then so be it. Over time
perhaps I can be educated into how to do this more "correctly" in
the middle end. Joseph seemed to have a good grasp on that so
perhaps when he has time we can talk about doing it better.

At this stage I'd rather change the front-ends and get the stuff
working than wait to engineer a middle or backend solution. I
dont mind ripping the front-end code out once (or if) we reach a
better solution in the backend.
