I'm standing by for the announcement that some caffeine-addled Boost metaprogramming madman has implemented the Rust borrow checker as a C++ template, or at least thinks that he may have, when the compilation completes sometime in the 2030s.
It's not clear how much boost.org magic they used. Failing that, a GCC extension could be needful.

Conclusion
We attempted to represent ownership and borrowing through the C++ type system, however the language does not lend itself to this. Thus memory safety in C++ would need to be achieved through runtime checks.
