Mailing Date 2026-05 Pre-Brno Author(s) Hui Xie, S. Levent Yilmaz, Louis Dionne, Patrick Roberts Target Audience LEWG SG9 Revisions R5 Tracking issue View on GitHub Abstract This paper proposes a new type-erased view: `std::ranges::any_view`. That type-erased view allows customizing the traversal category of the view, its value type and a few other properties. For example:
	P4205R0	Range-Based Searchers	Y. Li	SG9
Mailing Date 2026-05 Pre-Brno Author(s) Yihe Li Target Audience SG9 Revisions R1 Tracking issue View on GitHub Abstract Current inconsistency in the `std::ranges::search` API forces users to exit the Ranges world to use searchers and resort to using traditional STL algorithms instead, which is undesirable.
	P4211R0	Adaptors For Closed Ranges	Y. Li	SG9
Mailing Date 2026-05 Pre-Brno Author(s) Yihe Li Target Audience SG9 Tracking issue View on GitHub Abstract This proposal introduces a family of adaptors that convert closed ranges into half-open ranges, as expected by most other standard library facilities in C++, thus providing direct support for a range model that has been fundamentally incompatible with the C++ iterator model until now.
