Author: Arthur O'Dwyer Date: 2022-04-11T11:39:16-04:00 New Revision: d4e3c50b2bda796636bb283ab1a615f3333f75d9
URL: https://github.com/llvm/llvm-project/commit/d4e3c50b2bda796636bb283ab1a615f3333f75d9 DIFF: https://github.com/llvm/llvm-project/commit/d4e3c50b2bda796636bb283ab1a615f3333f75d9.diff LOG: [libc++] Define `namespace views` in its own detail header. Discovered in the comments on D118748: we would like this namespace to exist anytime Ranges exists, regardless of whether concepts syntax is supported. Also, we'd like to fully granularize the <ranges> header, which means not putting any loose declarations at the top level.
