Hmm, I like the later one better than the first one (of course the
object can be a union/merge!?) since it could cause some 
missunderstandings regarding *what* we are tracing otherwise.
(You have to "know" what objects already have been parsed etc...)
But otherwise I'd realy like it if you could implement this.

Yepp, I do. With these additions and the macro facility from the
isosurface patch one can make some realy *cool* include files.
Btw, I'd be glad to compile a macintosh port of your work when
you are finished (I assume you are using pc and/or unix) if you
like to (both of "this" and the "superpatch").
