Yes. To your average newbie, who doesn't already have
a very clear idea of exactly what call-by-value and
call-by-reference mean, using those terms doesn't
help.

Better to just explain how it works.

The problem is that said newbie is likely to seize
upon one of them and use it to try to describe to
some other newbie what sort of calling mechanism
Python uses, thus perpetuating the confusion.

I don't have a solution to that problem. :-(
