Ooh - I hadn't thought of that one Skip. I like it.

Of course, rather than just passing the function through, I'd probably want to check that it was actually a generator.

    def generator (f):
        assert f.func_code.co_flags & 0x20
        return f

    def silly_counter(n) [generator]:
        for i in range(10):
            yield n+i
