AFAIK it serves no purpose to allow that but does causes confusion, e.g.: There's no confusion there, nor does virtual devalue override in any way. Personally I would never use override *without* virtual, for the same reason I wouldn't omit virtual on an override in C++03. -- --- You received this message because you are subscribed to the Google Groups "ISO C++ Standard - Future Proposals" group.
