There is no guarantee that if and when the destructor or the custom 
delete will be called on garbage collected objects. If they do get 
called, the call order is not deterministic.

You can define the objects as 'scope' to force their destructors to be 
called when exiting the scope:

      scope Foo foo = new Foo();
