Hi Boian
I do not mind if this is done on a derived object. As Marco said earlier,  
one can do anything form his base root object. Just don't do it to the  
root class

Personally, I operate from a base class descending from TPersistent. Down  
the hierarchy I do have reference counted base class (done explicitly). If  
I want it implicitly, I would pass interface around. I do explicitly  
reference count some objects. However, in other cases (I posted earlier)  
this is a huge problem. Someone also mentioned the issue of race  
conditions in multithreaded environments. I can see this happening to me.  
I would not mind declaring a class implicitly reference counted (an all  
descendants, presubably). However, not TObject.
