std::filesystem::begin(directory_iterator), std::filesystem::end(directory_iterator)

directory_iterator begin( directory_iterator iter ) noexcept;

directory_iterator end( directory_iterator ) noexcept;

These non-member functions enable the use of directory_iterators with range-based for loops and make directory_iterator a range type (since C++20).
