	P3955R1	It's Scopes All the Way Down	R. Leahy	LEWG SG1	2026-08-10
Doc Date 2026-08-10 Mailing Date 2026-08 Unassigned Author(s) Robert Leahy Target Audience LEWG SG1 Revisions R0 Tracking issue View on GitHub Abstract The fundamental scope algorithm is `within`. It establishes a scope by running an enter scope sender. Thereafter it allows a child operation to run (in that scope since the exit scope sender has not yet run), and then before completing the overall operation runs the exit scope sender yielded by the enter scope sender.
	P4282R1	Away From co_yield For std::execution::task	R. Leahy	LEWG SG1	2026-08-02
Doc Date 2026-08-02 Mailing Date 2026-08 Unassigned Author(s) Robert Leahy Target Audience LEWG SG1 Revisions R0 Tracking issue View on GitHub Abstract The coroutine promise protocol shipped in C++20 not only banned `return_void` and `return_value` on the same promise type, but did so in an unusually restrictive manner [1]. Notably the aforementioned manner barred implementing the aforementioned mutual exclusion via mutually exclusive constraints.
	P4288R1	Stop the Decay	R. Leahy	LEWG SG1	2026-07-31
Doc Date 2026-07-31 Mailing Date 2026-08 Unassigned Author(s) Robert Leahy Target Audience LEWG SG1 Revisions R0 Tracking issue View on GitHub Abstract `std::execution` can be thought of as the realization of the asynchronous analogue of a synchronous function [1][2]. The sender is the function itself (with all arguments selected and applied), the receiver is the channel by which the function communicates with its caller (in the synchronous realm by returning or throwing), and the operation state is the “stack” (i.e. a collection of variables wit

Doc Date 2026-07-29 Mailing Date 2026-08 Unassigned Author(s) Robert Leahy Target Audience LEWG SG1 Abstract Under the status quo of the C++29 working draft one can write asynchronous code which branches synchronously:
