How is it expected behavior  in python, that

when I update position 0, 

it decides to update positions 1-infinity as well?

That is nonsense, and there is not a use case for this behavior. If you have already created the value, you have the value locally, and don't need N-REFERENCES to that thing. When calling functions as well, there will never be a time when you need more than 1 reference to the thing. 

How is this useful, and in what context could this ever be intuitive? If this is not a bug, it countermands the zen of python on almost every alternate line.
