This whole discussion is silly, IMHO.  The best idiom is:

    def foo():
        return []

If you really want an interator, then:

    def foo():
        return iter([])

Requiring that the type returned by foo be <type 'generator'> is
un-Pythonic and silly.  If you do want that, the best solution would be
the very clever suggestion of:

    def foo()
        if 0: yield None
