	P2953R3	Forbid defaulting operator=(X&&) &&	M. Taylor, A. O'Dwyer	SG17
Intent Proposal Mailing Date 2026-01 Unassigned Author(s) Matthew Taylor, Arthur O'Dwyer Target Audience SG17 Revisions R5 R4 Tracking issue View on GitHub Abstract Currently, [[dcl.fct.def.default]/2.5](https://eel.is/c++draft/dcl.fct.def.default#2.5) permits an explicitly defaulted special member function to differ from the implicit one by adding ref-qualifiers, but not cv-qualifiers.
	P3950R0	return_value & return_void Are Not Mutually Exclusive	R. Leahy	EWG SG1 SG17
Intent Proposal Mailing Date 2026-01 Unassigned Author(s) Robert Leahy Target Audience EWG SG1 SG17 Revisions R1 Tracking issue View on GitHub Abstract The standard specifies the effect of `co_return` statements in terms of equivalent statements within the context of a replacement body (§9.6.4 [dcl.fct.def.coroutine]). Like a regular `return` statement `co_return` statements have two distinct forms: Those that return `void` and those that return some value. These are specified as follows (§8.8.5 [stmt.return.coroutine]):
	P3960R0	Define copy-constructibility-from-bytes	M. Hoemmen, R. Arutyunyan	EWG LEWG SG1 SG17
Intent Proposal Mailing Date 2026-01 Unassigned Author(s) Mark Hoemmen, Ruslan Arutyunyan Target Audience EWG LEWG SG1 SG17 Tracking issue View on GitHub Abstract Given an object `src` of trivially-copyable type `T`, we can copy the object’s value representation to an array of bytes, and implicitly create a new `T` object (e.g., with `start_lifetime_as`) in the array of bytes. The result will hold the same value as `src`.
	P3963R0	Assignable lambdas with capture	R. Arutyunyan	EWG SG17
Intent Proposal Mailing Date 2026-01 Unassigned Author(s) Ruslan Arutyunyan Target Audience EWG SG17 Tracking issue View on GitHub Abstract This paper proposes making lambdas with captures copy assignable and move assignable when all captured entities are themselves assignable.
