I have problem with the location of hexadecimal memory address in

I agree they are "noise" mostly and difficult to distinguish when you
need to.
What if use serial numbers to differentiate instances?
<threading.BoundedSemaphore #5: 2/3>
where the serial number starts with 1 and increased for every new
instance of that type.
What would happen at a __class__ assignment?
IIUC class assignability is an equivalence relation amongst types:
serial numbers would have to be unique within the equivalence class, not
within the type. Otherwise, they would have to change (unlike id()), may
not round-trip if __class__ were assigned there and back.
