I still think they should stop adding new features and do what the C committee does in keeping the language stable over the decades which it will take to slowly die, as it should.
Can't the new-feature enthusiasts just make a new language, or join existing efforts at building new ones? C++ is already a mess of around 3.5 languages jumbled together. When will it stop?
Herb is working on something like that already. See his work on CppFront as an alternative syntax for C++:
