Seems like using `LHS` and `RHS` is more common (and more readable IMO) in Clang than `L` and `R`. ```suggestion auto AssignMostImportant = [](AffectedReason &LHS, AffectedReason RHS) { LHS = std::max(LHS, RHS); }; ``` https://github.com/llvm/llvm-project/pull/116374 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
