Portable SIMD is in C++26, and you can try it now
C++26 adds <simd>, a portable vector type that compiles to SSE, AVX, or NEON without a single intrinsic.

reflect_soa: AoS → SoA → AoSoA, one struct, three layouts
Corrected on 6 October 2026: reflect_soa is not a published library (its repository holds only a README), the embedded demo is a reduced hand-written stand-in, and the benchmark timings were never measured and are removed. The correction at the top has the details; the rest is kept as published.
