FWIW, this was my attempt at explaining names and values:
http://nedbatchelder.com/text/names.html, which I turned
into a PyCon talk this year: http://nedbatchelder.com/text/names1.html

It doesn't get quite as far as slice semantics, but deals with
"refers to" and "change", both of which are tricky to nail down
well.  Not sure I did... :)
