We are getting down the same road every couple of months. Please don't
explain Python's calling system with terms like "call by reference".
It's plain simple wrong. The correct term is "call by sharing" or "call
by object reference" although I myself don't use the latter term because
it sounds too much like "call by reference". Every time somebody tries
to explain Python with "call by reference", the person is confusing
himself and others.
