This paper proposes four range adaptors for set operations rated as Tier 3 in [P2760](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2023/p2760r1.html), namely `views::set_difference`, `views::set_intersection`, `views::set_union`, and `views::set_symmetric_difference`, to extend the breadth of Ranges.
