Interesting idea. Would be a lot of work to implement though, I guess.

Great idea, but what if your scene file takes 15 minutes to (re-)parse because
of heavy macro usage? And what if you are working on SDL code designed to write
to files (radiosity samples, photons, or just plain #write output)? I wouldn't
want POV to just start running *such* SDL code while it isn't "ready to rock"
yet.

(Or what if all the changes you want to do is just a few #defines that govern
whether your SDL file *does* #write or instead #read some stuff, in order to
switch from #write to #read mode... don't even want to think about it. Argh!)

No, I think the idea is intriguing, but prohibitive due to the power of POV's
SDL language.
