```suggestion std::same_as<leap_second&> decltype(auto) result = (b = a); assert(&result == &b); ``` Kinda pedantic, but we do it in several places and this ensures that we return the right type, and that we return `*this` from the operator. https://github.com/llvm/llvm-project/pull/82113 _______________________________________________ llvm-branch-commits mailing list llvm-branch-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/llvm-branch-commits
