	P3568R2	break label; and continue label;	J. Schultke	EWG SG22
Mailing Date 2026-05 Pre-Brno Author(s) Jan Schultke Target Audience EWG SG22 Tracking issue View on GitHub Abstract While C++ already has a broad selection of control flow constructs, one construct commonly found in other languages is notably absent: the ability to apply `break` or `continue` to a loop or `switch` when this isn’t the innermost enclosing statement. This feature is popular, simple, and quite useful:
	P3935R1	Rebasing <cmath> on C23	J. Schultke	SG22
Mailing Date 2026-05 Pre-Brno Author(s) Jan Schultke Target Audience SG22 Revisions R2 Tracking issue View on GitHub Abstract [[P3348R4]](https://wg21%2elink/p3348r4) rebased the C++26 standard on C23; it previously referred to C17. However, this process was deliberately left incomplete: some of the new C23 `<math.h>` features are only used by decimal floating-point types, or they require core language changes, etc.
	P4229R0	Canonical Parallel Scan: Expression and Observation Contracts for Reproducible Parallel Algorithms	A. Drakeford	SG6 SG18 SG22
Mailing Date 2026-05 Pre-Brno Author(s) Andrew Drakeford Target Audience SG6 SG18 SG22 Tracking issue View on GitHub Abstract Blelloch [Blelloch1990] identifies `reduce`, `scan`, and `transform` as core parallel primitives. P4016R0 demonstrated that efficient, reproducible reduction is achievable using a tree-based abstract expression.
	P4234R0	$identifiers	M. Wippich, M. Çağrı	EWG SG22
Mailing Date 2026-05 Pre-Brno Author(s) Matthias Wippich, Murat Can Çağrı Target Audience EWG SG22 Revisions R2 R1 Tracking issue View on GitHub Abstract One of the oldest and most widely supported extensions to C++ is allowing `$` in identifiers. This feature's origins predate both standard C++ and standard C. As GCC notes in its [documentation](https://gcc.gnu.org/onlinedocs/gcc/Dollar-Signs.html):
