constexpr reference operator*() const;

Effects: As if by:Iterator tmp = current;return *--tmp;

constexpr pointer operator->() const requires (is_pointer_v<Iterator> || requires (const Iterator i) { i.operator->(); });

Effects:

• If Iterator is a pointer type, equivalent to:return prev(current);
• Otherwise, equivalent to:return prev(current).operator->();

constexpr _unspecified_ operator[](difference_type n) const;
