Well, I know it is a little off-topic but POV-Ray (POV-Ray 3.6 at least) 
will happily parse the fragment

#declare Sphere = sphere { <0,0,0>, 1 pigment { rgb 1 } }
#declare Sphere_Child = sphere { Sphere pigment  { rgb 0 } }

Or even some weirder things like

#declare Sphere = sphere { <0,0,0>, 1 pigment { rgb 1 } }
#declare Sphere_Child = box { Sphere pigment  { rgb 0 } }

But I assume that it is just something unintentionally left behind in 
the code of the parser.
