Ah, now I understand what you mean. Nonetheless I don't see sane reasons 
for creating such (deeply nested) structures in real life code - records 
would serve the same (demonstrated) purpose.

I don't see much of a difference here. Objects without constructors can 
be declared as simple variables. Objects on the heap have no advantage 
over TObjects, so that class types can be used for that purpose everywhere.
