You terminology is off.  There is no such thing as an "assigned-to"
object in Python.  Assignments change bindings, not objects.

Take a step back and tell us what problem you are trying to solve.
Whatever it is, I'm sure we can think of a better solution than having
assignment depend on whatever object, if any, happened to be
previously bound to the same name.
