to Ranges Library  Converts container to container  E.g.: // Convert vector to set with same element type. std::vector vec{ 33, 11, 22 }; auto set1{ std::ranges::to(vec) }; // Convert vector words); // "Lorem", "ipsum", "dolor", "sit", "amet"73 Changes to Ranges Library  Finding the last element in a range:  ranges::find_last(): matching a given value  ranges::find_last_if(): for which a range starting at found element until end of the range, or {last, last} if not found74 Changes to Ranges Library  ranges::contains(): true if a range contains a given element  ranges::contains_subrange():

Plus, the types often end up boiling down to constants anyway!18 Part III: Clocks19 What is a clock 25MB) – we would have some very unhappy customers if their MSVC STL grew by such a large amount.
