I was wondering if there was a way to get an unique identifier to an
Object, e.g. as an Integer. There is a method asOop in Object (calling a
primitive), with comment "Answer a SmallInteger whose value is half of
the reciever's object pointer [...]", but as this is only half the
pointer, I am doubtful as to the uniqueness of this oop.
So, is there a way to get a guaranteed unique oop?
