        Why is it important to have an end but not to have a beginning?
Yup, you do have a point. Having an end is useful for traversing it from begin to end. Thus, the range concept applies to all iterators. It might be useful to think about having a beginning, for bidirectional ranges. It certainly needs more thought.
