What other languages use the same data model as Python?

It can be summed up in a less jargony way by saying that all
data is stored in heap-allocated objects, and variables refer
to objects rather than containing them directly. Everything
else follows from that.

Pretty much any dynamically-typed language: Lisp, Scheme,
Smalltalk, Snobol, Icon, Postscript, Ruby, Lua, ...

Some languages have it for some data types but not others.
Java, VB, Objective-C come to mind.
