std::mdspan is C++23's non-owning multidimensional view. It separates storage (a flat buffer you already have) from shape (extents) from indexing (a layout), so one std::vector becomes a 3x4 matrix with real m[r, c] indexing and no copy. GCC 16.1 ships it, and Mark Hoemmen's C++Now 2026 keynote is on where it and standard parallelism go next.
