    Ah, right, with you, so far...

    Would POV choke on something like this ?

// Create an 'empty' glow object.
#declare glowObj=
object {
 glow {...}
}

// Union our glow with other non-glowing objects
union {
 object { .... } // non-glowing stuff
 object { glowObj }
}

    If you could fix it to work like that, then it should also be possible
to allow this :

// Union an explicit glow object with non-glowing stuff.
union {
 object { .... } // non-glowing stuff
 object { glow{...} }
}

    Dunno if it's any better like that - it does save adding new keywords to
the language (but, then, is that a bad thing ?) and it also seems more
intuitive to me (but, then, intuitiveness is subjective) - any thoughts ?
