@voklen What makes it complicated if when you have a problem with 5 sub-issues, and multiples possible solutions but none of them solves all 5 sub-issues. Even worse, some being more efficicient to solve 1 or 2 sub issue while making the 4th or 5th much worth. If your idea can take care of such complicated and heated debates that would be amazing.
@onlinepersona @snaggen Indirectly it can. Recent studies showed that old code is very unlikely to have security issue. This means that if all new code can be in Rust, while keeping the old code in C++ will be much more secure that rewrite all C++ (because by definition rewrite have more bugs since its new code). So interoperability is both safer and cheaper.
