You could create a language in such a way, but it would be quite
strange...actually, JavaScript is a little similar. But none of the
syntaxes I've seen suggested for POV would do it this way.

I think you might be referring to my "#declare MyObj = object {MyObj
translate...}" example. I would actually prefer some kind of wrapper,
though maybe not of that exact form. Something like:
scene {
MyObj;
AnotherObj;
AndAnotherOne;
SomeProcedureThatReturnsAnObject();
ObjectMaker.MakeAnObject();
}
Basically, any statement that results in an object puts an object into
the scene when used within a scene {} block. Outside a scene block, the
object just gets ignored. Otherwise you'll run into annoyances when you
call something that returns an object that is only desired some of the
time. Say you have a procedure that does something to an object and
returns that object for convenience, but you sometimes need to call it
but don't need the returned object. Without the scene{} block
restriction, you'd have to do something like declare a dummy variable
just to hold the object you don't want...annoying.
I also think it makes things a bit clearer to have some kind of wrapper
for the object name.

Well, it won't make the internals of a lens flare system any easier for
non-coders to understand, but it will make it easier for them to use it.
Objects are typically seen as "black boxes", they can be very complex
inside but nobody has to care about that, they only use the stuff on the
outside.

I don't think so. It will mean more is possible entirely within POV
script, so the "data crunchers" won't have to go to external tools, and
the casual users have a much shorter distance to go before they can
understand and create similar things. POV-artists and POV-coders, rather
than POV-artists and C++/Java/Python-coders-who-export-POV-code.
