What other languages use the same data model as Python?

Eh, that example doesn't say what you think it does. It has the same
behavior in C: http://ideone.com/Fq09N . Python is pass-by-value in a
meaningful sense, it's just that by saying that we say that the values
being passed are references/pointers. This is maybe one level of
abstraction below what's ideal, but Scheme, Java, etc. share this
terminology. (Ruby calls it pass-by-reference AFAIK. Whatever, a rose
by any other name...)
