When transitioning code fromcoroutines-ts to c++20, it can be useful to add a using declaration tostd::experimental pointing to std::coroutine_traits. This permitsthat use by checking whether lookup in std::experimentl finds adifferent decl to lookup in std. You still get a warning aboutstd::experimental::coroutine_traits being a thing, just not an error.Reviewed By: ChuanqiXuDifferential Revision: https://reviews.llvm.org/D115943 List of files: /llvm-project-15.0.7/clang/test/SemaCXX/coroutine-mixed4-exp-namespace.cpp Sat, 25 Dec 2021 18:30:42 +0000 Nathan Sidwell <nathan@acm.org>
