Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Hewill Kang Target Audience SG9 SG23 Tracking issue View on GitHub Abstract This paper provides the `at()` method to `ranges::view_interface` to provide a safe access method for the view class. Revision history R2 Rename the feature-test macro based on LEWG feedback. R1 Added wording for freestanding. R0 Initial revision. Discussion Currently, the committee adopted [P2821](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2023/p2821r4.html) in C++26, which adds a missin
	P3059R2	Making user-defined constructors of view iterators/sentinels private	H. Kang	LEWG SG9
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Hewill Kang Target Audience LEWG SG9 Tracking issue View on GitHub Disposition Date 2026-03Adopted Abstract The exposure of user-defined constructors for iterators/sentinels in `<ranges>` currently does not follow consistent rules, which is reflected in the fact that some of them are public and some are private. This paper disables their visibility to comply with best practices.
	P3732R2	Numeric Range Algorithms	R. Arutyunyan, M. Hoemmen, A. Kukanov, B. Lelbach, A. Majumder	SG1 SG9
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Ruslan Arutyunyan, Mark Hoemmen, Alexey Kukanov, Bryce Adelstein Lelbach, Abhilash Majumder Target Audience SG1 SG9 Tracking issue View on GitHub Abstract We propose `ranges` algorithm overloads (both parallel and non-parallel) for the `<numeric>` header.
	P4049R0	Relaxing and extending std::copy	G. D'Angelo	LEWG SG1 SG9 SG18 SG23
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Giuseppe D'Angelo Target Audience LEWG SG1 SG9 SG18 SG23 Revisions R1 Tracking issue View on GitHub Abstract In this table we’re summarizing the status quo and the changes brought by the options and extensions illustrated above. The table refers to `std::copy`, but similar changes are expected for the other algorithms of the family.
	P4102R0	Container insertion and erasure should be allowed to relocate	G. D'Angelo	LEWG SG9
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Giuseppe D'Angelo Target Audience LEWG SG9 Tracking issue View on GitHub Abstract The sequence containers `vector`, `inplace_vector` and `deque` store their elements in contiguous storage (or, in the case of `deque`, in blocks of contiguous storage). When an element is erased from the middle of such a container, the elements after the erased position must be shifted to fill the gap. Similarly, when an element is inserted in the middle, the existing elements must be shifted to m
	P4179R0	view_interface::[c]rbegin()	H. Kang	LEWG LWG SG9
Intent Proposal Mailing Date 2026-04 Post-Croydon Author(s) Hewill Kang Target Audience LEWG LWG SG9 Tracking issue View on GitHub Abstract This paper provides `rbegin()`/`rend()`/`crbegin()`/`crend()` methods to `ranges::view_interface`, making its interface more symmetric with the existing `cbegin()`/`cend()` members and enhancing convenience for views. Revision history R0 Initial revision. Discussion In C++23, `view_interface` added `cbegin()`/`cend()` members to improve const-correctness and interface consistency. However, it stil
