But that only works when you *have* names. Many
objects in a typical Python program don't have
any names bound to them -- contents of lists,
tuples, dicts, etc.

You need some concept of boxes with pointers
in them to make sense of all those. Once you
have that, it seems natural to me to think
of variables as named boxes.

Indeed. I'm quite happy with the mileage I
get from my named boxes. About 50mpg on a
good day, I think. :-)
