Perfectly understandable. What it *does* allow for is to apply texture
(pigment, etc.) and/or use transformations, whatever else legal, so that any
premade object can always be reobjected (sorry, only way I could sum that up
in a word)and those things done to it.

#declare Sphere=
object {
    sphere {0,1}
}

#declare GreenSphere=
object {
    Sphere
    pigment { green 1 }
}

#declare MovedGreenSphere=
object {
    GreenSphere
    translate y
}

And that could go on and on. Probably best described as a container for
using object modifiers (per all other rules of how POV-Ray works) but only a
part of CSG if 'inverse' is used in it, or identifier needing a wrapper. Or
at least I think I can say that and not be wrong.  :-)
