The axe situation doesn't arise in Python, because "same
object" in Python is a concept that only applies to objects
existing at the same time.
There's no way to even ask a question like "does a refer
to the same object that b did a second ago", because
the only way to test object identity is to use the
'is' operator, which takes two expressions evaluated
at the same time.
