	P2964R2	Allowing user-defined types in std::simd	D. Towner, R. Arutyunyan	LEWG SG6
Intent Proposal Mailing Date 2026-02 Pre-Croydon Author(s) Daniel Towner, Ruslan Arutyunyan Target Audience LEWG SG6 Revisions R5 R4 R3 Tracking issue View on GitHub Abstract The C++ standard library includes data-parallel types in the `<simd>` header, currently restricting element types to a closed list: arithmetic types and `std::complex` specializations. This paper proposes a minimal change to the specification in which the closed list is replaced with trait-based constraints that handle all existing types while naturally extend support to enumerations, `std::byte`
	P4010R0	Add funnel shift operations to bit header	D. Towner	SG6
Intent Proposal Mailing Date 2026-02 Pre-Croydon Author(s) Daniel Towner Target Audience SG6 Revisions R1 Tracking issue View on GitHub Abstract This paper proposes adding funnel shift operations to the C++ standard library. Funnel shifts concatenate two integer values, shift the concatenated result, and extract bits. This is a fundamental primitive bit operation with widespread use across many domains including cryptography, hashing, compression, and pseudo-random number generation.
