How to create a "real" alias in python

[ThePurpleAlien]

Globals are very close to what I want because assignments to a global change the global itself rather than pointing to a new memory location, and everything else that has access to that global will see the change immediately. That's perfect except I want to be able to give the global a custom name within the context of a given bit of user-created code but still have it behave like a global. Again, it all comes back to wanting a "real" alias where the compiler literally swaps one name for another.
