	Perhaps it's because you tried learning OOP from C++/Java?

	I'm sure you think in OOP all the time with POV-Ray. You create a 
sphere. It's an object with certain properties (texture, location, etc). 
Now let's say you want to rotate the sphere, does it hurt so much to do 
something like:

mysphere.rotate(45)

	Let's say you want to have lots of balls in your scene. You want some 
to be red, some blue, and some green. And some of _those_ you want to be 
translucent.

	So you create your "basic" ball as a sphere with little texture. You 
subclass it to create two kinds of balls: "solid" and "translucent". In 
terms of actual code, you just create a new object that is the subclass 
of your "basic", and you merely add to it the texture that makes it 
translucent.

	Then you can subclass each to get the red, blue and green balls.
