I hope you can make use of: This is cool! It is intended to used this
way! Just do it!

If you take a look at at org/python/util/PythonInterpreter and its set()
method you will see that it too takes an Object as a generic value.

    public void set(String name, Object value) { ... }

This method is solving exactly the same problem of setting a local
variable in a python namespace.

Yes. Very nice.
