I consider the values to be references to objects.  But as you say...

It's really just about terminology.  Personally I'd find it confusing
if I were new to Python and heard someone say that Python has
bindings-of-some-sort, but not variables.  My background is compilers
and programming language semantics, so maybe I'm also just being
overly pedantic.
