	P2287R6	Designated-initializers for base classes	B. Revzin	EWG
Mailing Date 2026-07 Post-Brno Author(s) Barry Revzin Target Audience EWG Tracking issue View on GitHub Disposition Date 2026-06 Abstract [[P0017R1]](https://wg21.link/p0017r1) extended aggregates to allow an aggregate to have a base class. [[P0329R4]](https://wg21.link/p0329r4) gave us designated initializers, which allow for much more expressive and functional initialization of aggregates. However, the two do not mix: a designated initializer can currently only refer to a direct non-static data members. This means that if I have a

Mailing Date 2026-07 Post-Brno Author(s) Barry Revzin, Bruno Cardoso Lopez, Zach Laine, Michael Park Target Audience EWG Tracking issue View on GitHub Abstract C++ is a language built on statements. `if` is not an expression, loops aren’t expressions, statements aren’t expressions (except maybe in the specific case of `expression;`).
	P4101R1	Consteval-only Values for C++26	B. Revzin, P. Dimov, D. Vandevoorde, D. Katz	EWG CWG
Mailing Date 2026-07 Post-Brno Author(s) Barry Revzin, Peter Dimov, Daveed Vandevoorde, Dan Katz Target Audience EWG CWG Revisions R0 Tracking issue View on GitHub Disposition Date 2026-06 Abstract The Reflection design from [[P2996R13]](https://wg21.link/p2996r13) was based on a model of having consteval-only types to prevent reflections from leaking to runtime. But we’ve run into issues and limitations with that approach, so we propose that, for C++26, we change instead to a consteval-only value model. This solves the same problems, but has additional benefits.
	P4259R0	The name of the floor division function should probably have floor in it	B. Revzin	LEWG
Mailing Date 2026-07 Post-Brno Author(s) Barry Revzin Target Audience LEWG Tracking issue View on GitHub Abstract In 1962, Kenneth Iverson introduced the names “floor” and “ceiling”, and the syntax `⌊x⌋` and `⌈x⌉`, for operations that return the greatest integer less than or equal to `x` and the smallest integer greater than or equal to `x`, respectively. Since then, these names have become broadly used in math and programming.
