Yes, that sounds good except for the problem of how to pass the object to
the second form.

This reduces generality because the second form can't use optional
arguments, and it seems a little strange to say that the second value is a
form minus its last argument.
What I had in mind was ((LAMBDA (object) ...code...)). But I like your
suggestion of evaluating the form in an environment where * is bound to the
object better. Other people should check me on this, it might just be that
you appealed to my sense of hackish kludgery.
It would be nicer if we could just use a function, but the last proposal I
saw for what you could use as constants in COMPILE-FILE said you could not
use functions. We could use a LAMBDA expression, I suppose.

Yes, I would like to see that.
I'll update it based on all the received comments as early as I can next week.
