There is no such constraint that object destruction is LIFO.

Especially in a collection there is no requirement that destruction occur in any particular order.

The containership model of VFP is the only place where an innermost to outermost or outermost to innermost order construction/destruction applies at all. Within the same level of containership there is no LIFO requirement.
