Mailing Date 2026-07 Post-Brno Author(s) Daniel Towner, Ruslan Arutyunyan Target Audience LEWG SG6 Revisions R4 R3 R2 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 of built-in vectorizable types: arithmetic types and `std::complex` specializations. This paper proposes a minimal change to the specification in which this list is extended. Firstly, `std::byte` is added to the closed list as a standard library type with fixed seman

Mailing Date 2026-07 Post-Brno Author(s) Mateusz Pusz Target Audience SG6 Revisions R0 Tracking issue View on GitHub Abstract [[P3045R7]](https://wg21.link/p3045r7) proposes a C++ quantities and units framework built on two core abstractions: `quantity` (displacement vectors) and `quantity_point` (points in an affine space). Real-world experience with the [[mp-units]](https://mpusz.github.io/mp-units) reference implementation, together with feedback from SG6, BSI, ANSI, and the broader C++ community, shows that this
