One can simply ditch the C++ backward compatible features into an "unsafe" part of C++. That's exactly what the talk given by Herb at the CppConf is trying to address. All the old unsafe part of C++ will trigger errors or warnings. But if truly necessary one will be able to disable these protections!

And by breaking backwards compatibility so heavily, it effectively makes the new safe C++ into a different language.
