Well, if you restrict yourself to functions and objects,
you can implement the assigning from within the code:

Instead of writing:

    x = func('x')

you'd write

    func('x')

and have func register itself with the globals under the given
name:

    def func(bindto):
        value = 'Hello World !'
        globals()[bindto] = value
        return value

    func(bindto='x')

    >>> x
    'Hello World !'

I don't see how that could work without being more explicit
about the intention.
