So how about
	$factory->findObjects ('@Testing', {
	       CellTypeList.CellType => ['in', 
['microglia','muller','ganglion']]
        });

I don't disagree with you.  I'm just trying to point out ways around  
this limitation so you can do what you need sooner.
This kind of feature would not be trivial to implement.  Somebody  
would need to dedicate a considerable chunk of time to do this  
(possibly a week or two), and realistically I don't see it happening  
soon (I can only speak for my group).  Now if someone else were to  
volunteer, we would certainly help them out in any way we could.
