Whether a language can implement a swap procedure like that is
not the same question as whether the language variables are
references or not.

Since the topic was whether or not python has reference variables,
is seems there is no need to bring this swap procedure into it at all,
instead of turning it around and pretending it was about the
swap procedure.
