Very hard to say. LISP has OOP too, Google for CLOS.
Operator overloading is something to avoid anyway, IMHO, just like static typing is something to avoid if you need fast development, on schedule and the like. LISP has one thing that Python does not have: LISP code is LISP data. A thorough study comparing LISP and Python in this respect would be welcome. -- http://mail.python.org/mailman/listinfo/python-list
