许杰友 Jieyou Xu (Joe) 1419f79acf Rollup merge of #135237 - dianne:match-2024-cleanup, r=Nadrieril ... Match Ergonomics 2024: document and reorganize the currently-implemented feature gates The hope here is to make it easier to adjust, understand, and test the experimental pattern typing rules implemented in the compiler. This PR doesn't (or at isn't intended to) change any behavior or add any new tests; I'll be handling that later. I've also included some reasoning/commentary on the more involved changes in the commit messages. Relevant tracking issue: #123076 r? `@Nadrieril`		2025-01-20 12:38:31 +08:00
