I had thought of that but decided not to bother. From https://en.cppreference.com/w/cpp/language/fold: ``` op - any of the following 32 binary operators: + - * / % ^ & | = < > << >> += -= *= /= %= ^= &= |= <<= >>= == != <= >= && || , .* ->* ``` Because `<` and `>` are on the list, we still wouldn't be able to tell if `...>` is part of a fold expression. Also, I don't like the overhead of up to 32 comparisons. https://github.com/llvm/llvm-project/pull/91045 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
