Hmm, I use something more like "eval_pattern(object {MyObject})" when I 
do this...actually, I wrap it in a macro.
This would make your code shorter and probably slightly reduce parse 
time(though the use of a macro might counteract that benefit), the main 
advantage is that it is shorter and easier to read.
Instead of:
   #declare obfun=pigment {object {MyObject color Black color White}}
...
    #local blank=eval_pigment(obfun,place);
    #if (blank.x>0)

My version would be:
#macro InObj(Pt, Obj) eval_pattern(object {Obj}, Pt) #end
...
    #if(InObj(place, MyObject))
