* @brief The regular array member iterator * * This method delivers an array iterator pointing to the member with the given indexes, * provided the array is a regular one. If the array is not regular this method * will deliver the same iterator than begin (). * There is no end() method. Rather use the at_end() method * of the iterator to determine the end of the sequence.
