I'm not sure what you mean by "accessing an unbound variable" means in
the context of this thread, or any context for that matter. Nothing of
the kind is happening in the OP's example. What's happening is that a
class attribute is initialized, incremented, and decremented. Using
class attributes is common practice.

The problem, as I explained in my previous post, is that the class
attribute is looked up via a global name of the class, and that name may
or may not have disappeared in a puff of logic by the time the
instance's __del__ method is run in the VM shutdown sequence.
