constexpr std::iter_const_reference_t<Iter> operator*() const;
(1) (since C++23)
constexpr const auto* operator->() const

    requires std::is_lvalue_reference_v<std::iter_reference_t<Iterator>> &&
        std::same_as<std::remove_cvref_t<std::iter_reference_t<Iterator>>,

                     value_type>;
(2) (since C++23)

Returns a reference or pointer to the const version of the current element.

1) Returns static_cast<std::iter_const_reference_t<Iter>>(*base()).
2) If Iter models contiguous_iterator, returns std::to_address(base()); otherwise, returns std::addressof(*base()).

[edit] Return value

1) Reference-to-const that refers to the current element. The result may be a prvalue (e.g. if *base() is a prvalue).
2) Pointer-to-const that points to the current element.
