Isn't it the case that *everything* is passed by reference in Python?
The only important thing is whether the object for which the reference
is being passed is mutable or not. For non-mutable objects, it looks
a lot like pass-by-value and can lull you away from your state of
vigilance about such issues. Then you go and pass in a mutable like
a list and you get into trouble.
