What other languages use the same data model as Python?

It seems to me that manually referencing and dereferencing in C is
more akin to decorating functions like this:

def foo(x):
    do_stuff()

foo = decorate(foo)

On the other hand, the @ syntax is analogous to declaring reference
types in C++ (e.g. "int &" as opposed to "int *").  In both cases you
have to tell the interpreter / compiler that you want to use the
decoration / pass-by-reference feature, and the actual work is done
for you automatically.
