Viewing The World Through Array-Shaped Glasses
summary
Claims that C++ needs a unified view for contiguous data and presents N3851 which defines array_view and strided_array_view, multi‑dimensional index and bounds types, slicing/sectioning semantics and pointer‑like cheap copies. Shows a concrete 3x3 edge‑detect demo lifted from linear vector into a 2D view, replaces nested loops with single index iteration, and maps indices to execution agents for parallel STL. Provides working headers and a Windows parallel STL implementation.
