Actually, I think it might work fine if everything has a default value
and is considered to exist at the opening { brace.
If that were so, this:
sphere {min_extent(self), 1}
would center the sphere on the min_extent of the default sphere. I don't
know what it would do for meshes or CSG though, and it might not give a
perfectly obvious result all the time...

I'm not sure what you are trying to say about implementing it as a
render-time variable...most of the uses I can think of for it are at
parse time.
