Ah-ha, that clears it up. I had forgotten that.
I realize now where I got confused: saying "pass by reference" is
entirely different from saying "pass a reference". The same applies to
the word "value". So Python passes by value, since the assignment
operator within a function never modifies the caller's binding.
