   * @a safe sequences that track the iterators that reference the
   * sequence, so that the iterators are notified of changes in the
   * sequence that may affect their operation, e.g., if the container
   * invalidates its iterators or is destructed. This class template
   * may only be used by deriving from it and passing the name of the
   * derived class as its template parameter via the curiously
   * recurring template pattern. The derived class must have @c
   * iterator and @c const_iterator types that are instantiations of
   * class template _Safe_iterator for this sequence. Iterators will
   * then be tracked automatically.
