That's not going to happen. There's just too much friction to reach consensus on how to move the language in that kind of direction. It's like trying to get a centipede to walk to the food when none of the legs can agree on the best path to take. Before that happens, it's much more likely that some other language that interoperates well with C++ will reach a useful state (with regards to IDE support and other tools) and will be embraced by the community. By "community" I don't just mean hobbyists, but the major members of the C++ committee: Microsoft, Google, Nvidia, Intel, etc. That language might be Rust or it might be some other language that's yet to appear. It might not even be a single language, but several. I personally think Rust is not a suitable successor to C++.
