I would expect that to work (it is something I would want to be able to 
do - otherwise you would need a finalise method - yuck), I can't recall 
if I have done it though?

a should still be detected as having objects referencing it until the 
MyClass destructor is finished I would think (if the delete a wasn't 
there). Otherwise you would not be able to rely on any class properties 
as still existing in its destructor (ie a.method() could cause an 
exception as well).
