I might have misinterpreted what you mean as “standard” (I was originally thinking like you meant that the standard dictates all operations must be safe and doing things like the unsafe/unchecked option references would be outside the standard). I realized that you might mean it like it should be the default behavior, so correct me if I’m wrong there.

Yeah I agree that sane defaults would be nice and that things like unchecked accesses should be more explicit. Having linear types to properly enforce issues with things like use-after-move would also be awesome. I don’t know that anyone has ever accused C++ of being particularly ergonomic. Sum types and pattern matching would be awesome.

Nothing wrong with being a Rust fanboy :), I have written some (https://github.com/afnanenayet/diffsitter).
