DeVault: Announcing the Hare programming language

In modern C++ you're going to have a lot more cases where ownership is represented via a smart pointer (std::unique_ptr or std::shared_ptr), which is something Rust can get behind easily, but Zig can't really help you with. So it's probably going to shade over, C++ code that's mostly 15-20 years old may be happier to work with from Zig, while C++ code that's all written after say C++ 14 might be much easier to work with from Rust via one of the C++ FFI libraries like cxx which understands the standard library smart pointers.
