If you're learning a new language, you're almost certainly
going to learn how assignment works in that language before
you get as far as worrying about parameter passing. I

That's the point of the term -- it's the same as whatever
assignment does in the language concerned.
This is true of *every* language I know of that uses the
term "call by value" in its official documentatio

uni, where it was defined in mathematical t

Doh! Using int(c) didn't occur to me and I didn't know about
math.factorial. Notice also that WJ hasn't yet dared posting his crap
