Interesting concept.
Trying to think of a situation where the presence of objects can only be
determined during a render...
Failing...
I think that would imply that the order of evaluation would be relevant,
which would make parallel rendering impossible.
Perhaps not a good example. But feel free to come up with another. I
think such examples are vital in determining how intertwined the
language has to be.
Perhaps one case could be that you want to create a marble bas relief by
creating a displacement map from another scene.
Can I donate this one to Fabien's list?
