In the C++ language itself, there are only two features that violate the zero-overhead principle, exception handling and RTTI – and, unsurprisingly, these are also the only two C++ language features that every C++ compiler has switches to turn off and that are regularly discouraged or even banned. This matters because not using these features is the largest current cause of fragmentation of the C++ community into incompatible dialects, and the cause of recurring problems including type confusion security vulnerabilities arising from “didn’t down-cast using dynamic_cast because that would be too slow.” This talk is about ongoing long-term efforts to try to unify the community in this area, not by replacing exceptions and RTTI, but by doubling down: fully embracing exceptions and RTTI, and improving them so they can be zero-overhead too. — Herb Sutter Herb is an author, designer of several Standard C++ features, and chair of the ISO C++ committee and the Standard C++ Foundation.
