Those languages are all pretty different from C++, right? I'm assuming the new C++ would be very similar to old C++ with a bunch of things "considered harmful" removed.
Well I’ve seen at least three recent CppCon talks where they say that ‘for’ loops are harmful and a template function should be used always, so I would hope there would not be a removal of these things, just a non-concern with requiring that changes don’t break the compilation of 10+ year old code.
