"What is a view?" http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p2415r2.html https://github.com/cplusplus/draft/pull/5010/files This was a late-breaking (Oct 2021) change to C++20. The only thing missing from this patch is that we're supposed to bump the feature-test macro from #define __cpp_lib_ranges 202106L to #define __cpp_lib_ranges 202110L but we can't do that because we don't implement all of 202106 Ranges yet.
