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

Abstract `std::simd` includes scalar overloads for a few operations where variants of a function or operator accept a scalar where a `simd::vec` value would otherwise be expected. Recent papers continue this theme, with better shifts [P3793R1] and funnel shifts [P4010R0] adding scalar-operand variants. This has inadvertently created an expectation that every new operation should provide scalar overloads to
