There I go, reimplementing the wheel again. Guess I didn't pay enough
attention to "What's New In 2.2". Thanks for the pointer. It appears
we don't need that scanner() method after all.

However, from my point of view it was a good exercise, because now I
know how easy it is to make an iterator.

Thanks again
