Is that not the same in C++ and in most languages?

... until someone else in your team uses it in your code base. And then you need to know about it in Rust as well.

The difference is that with rusts safety you can to some degree "try thinks out". Which doesn't work with C++ as you might have hidden UB.

Also C++ has a bunch of "hidden" features and unexpected interactions with other features and UB like e.g. forward guarantee because of which `while(1);` is UB.
