  You know, it suddenly "clicked".  What you are after, Fare, is a backend
to the HLL.  That's it.  Nothing more and a technology that's been around
for quite come time (even Microsoft was doing this in the mid 80s for all
their languages).

  I would have assumed something like this, had you, Fare, not made such a
big production out of it, making it, in my view, into something so different
that it needed discussion.  It doesn't.  

  Or, at least not to the degree you think it might.

  Or, if the LLL is going to be so different from CPU to CPU, then why even
bother with it?  You might as well go HLL -> assembly and be done with it.

  Then why limit the LLL programmers in the tools required?  Why force the
LLL to be so poor then?

  Personally, I feel you'd (Fare and the other HLL people) be better off
defining the HLL, and maybe implimenting it under an existing system, and
leave the OS portion till you've hashed out what you want in the HLL and the
