constexpr move_iterator& operator++();
Effects: As if by ++current.
Returns: *this.
constexpr auto operator++(int);
Effects: If Iterator models forward_­iterator, equivalent to: move_iterator tmp = *this; ++current; return tmp;
Otherwise, equivalent to ++current.
constexpr move_iterator& operator--();
Effects: As if by --current.
Returns: *this.
constexpr move_iterator operator--(int);
Effects: As if by: move_iterator tmp = *this; --current; return tmp;
constexpr move_iterator operator+(difference_type n) const;
Returns: move_­iterator(current + n).
constexpr move_iterator& operator+=(difference_type n);
Effects: As if by: current += n;
Returns: *this.
constexpr move_iterator operator-(difference_type n) const;
Returns: move_­iterator(current - n).
constexpr move_iterator& operator-=(difference_type n);
Effects: As if by: current -= n;
Returns: *this.
