Normally when something #declared is called, a copy of it is created. For a
world that would use way to much memory. Some other approach should be
found.

Once a world is created I think it should indeed "exist" (though not
necessarily visibly), and not just be waiting to be called.

I see the point although I'd prefer a solution where a world didn't have to
be in a separate file. Currently no features in POV-Ray *require* separate
files (except images etc.). Include files are optional and never required.

#world (WorldIdentifier)
   ...anything goes here...
#end

How about this?
It could also be used like:

#world (WorldIdentifier)
   #include "worldfile.pov"
#end

I think "universe" is too specific, at least the scientific sense of the
word. The feature would probably often be used just to make different "sets"
"stages" or "scenes". Actually I think "scene" would be better than both
"world" and "universe" if it wasn't for the fact that POV-Ray files are
often referred to as "scene-files" which would cause confusion...
