	P0876R23	fiber_context - fibers without scheduler	O. Kowalke, N. Goodspeed	CWG LWG	2026-05
Intent Proposal Mailing Date 2026-05 Unassigned Author(s) Oliver Kowalke, Nat Goodspeed Target Audience CWG LWG Revisions R24 R22 Tracking issue View on GitHub Abstract This paper proposes a minimal API that enables stackful context switching without the need for a scheduler. The API is suitable to act as building-block for high-level constructs such as stackful coroutines as well as cooperative multitasking (aka user-land/green threads that incorporate a scheduling facility).

I’ve been hand-embedding data in executables for NEARLY FORTY YEARS now. — Guy "Hatcat" Davidson, June 15, 2018

	P3666R4	Bit-precise integers	J. Schultke	LEWG CWG	2026-05
Intent Proposal Mailing Date 2026-05 Unassigned Author(s) Jan Schultke Target Audience LEWG CWG Revisions R3 Tracking issue View on GitHub Abstract In distant history, there have been various attempts at standardizing multi-precision integers in C++, such as [[N1692]](https://wg21%2elink/n1692) "A Proposal to add the Infinite Precision Integer to the C++ Standard Library", [[N1744]](https://wg21%2elink/n1744) "Big Integer Library Proposal for C++0x", and [[N4038]](https://wg21%2elink/n4038) "Proposal for Unbounded-Precision Integer Types", al
	P3668R3	Defaulting Postfix Increment and Decrement Operations	M. Taylor, A. (Waffl3x)	CWG	2026-05
Intent Proposal Mailing Date 2026-05 Unassigned Author(s) Matthew Taylor, Alex (Waffl3x) Target Audience CWG Revisions R4 Tracking issue View on GitHub Abstract Postfix increment and decrement operators have a default behaviour which already exists in the mind of every C++ developer - make a copy, increment/decrement the original, and return the copy. The canonical implementation of this default can always be expressed entirely in terms of other operations (prefix increment/decrement and copy-construction), in a manner which is entirely agnostic to any ot
	P3891R1	Improve readability of the C++ grammar by adding a syntax for groups and repetitions	J. Schultke	CWG LWG	2026-05
Intent Proposal Mailing Date 2026-05 Unassigned Author(s) Jan Schultke Target Audience CWG LWG Tracking issue View on GitHub Abstract The current C++ syntax notation as specified in [[syntax]](https://eel.is/c++draft/syntax) and summarized in [[gram]](https://eel.is/c++draft/gram) has only a handful of features:
	P4136R2	#line is not in line with existing practices	C. Jabot	CWG	2026-05
Intent Proposal Mailing Date 2026-05 Unassigned Author(s) Corentin Jabot Target Audience CWG Revisions R1 R0 Tracking issue View on GitHub Abstract line-directive: # line pp-tokens new-line The string-literal of a #line directive, if present, shall be a character string literal. The line number of the current source line is the line number of the current physical source line, i.e., it is one greater than the number of new-line characters read or introduced in translation phase 1[lex.phases] while processing the source file to the current prep
	P4176R1	Grammar non-terminals for postfix-expressions	V. Serebrennikov	CWG	2026-05
Intent Proposal Mailing Date 2026-05 Unassigned Author(s) Vlad Serebrennikov Target Audience CWG Revisions R0 Tracking issue View on GitHub Abstract 7.6.1 [[expr.post]](https://wg21.link/expr.post) lists all the grammar at the top, while the rest of the subclause resorts to either quoting the grammar or describing it with words. This paper aims to improve the situation, introducing new non-terminals and putting their definitions in the respective subclauses.
