Let's not go into the discussion. I know the semantics of C++ and I know
the semantics of Python, but I don't what semantics you're calling 
'call-by-foo' and which you're calling 'call-by-bar'. :)

Oh, well, look up a thread in groups.google.com. Nobody was agreeing
on it. Decades-old books were referenced, but that didn't seem to 
give some conclusive evidence either. :)

I agree Python's argument passing mechanism is nice, whatever we'll call it. :)
