23 Ranges: slide & stride
summary
Three proposed C++23 range adaptors expose a two-parameter signature (size and range) and produce a range of ranges: sliding (overlapping windows), chunk (nonoverlapping blocks with a final partial block), and stride (every kth element). Examples show k=4 on 0..9 and the exact outputs, and the talk demonstrates that Kotlin’s windowed maps to these by choosing size and step so chunk/sliding/stride are implementable from one general primitive. It surveys cross‑language names and argues for slide/windowed consistency and references range‑v3 and GitHub examples.
