Nice thing about Rust is not that you cannot write such code, it is you know exactly where you used peaky memory or re-interpreted something as a unsigned integer or replaced your program stack with something else. All of such cases require unsafe blocks in Rust. It is a screaming indicator "here be dragons". It is the do not press this red button unless you intend to.

In C and C++ no such thing exists. It is walking in a minefield. It is worse with C++ because they piled so much stuff, nobody knows on the top of their head how a variable is initialized. The initialization rules are insane: https://accu.org/journals/overload/25/139/brand_2379/

So if you are doing peaky memory stuff with complex partially self-initializing code in C++, there are so many ways of blowing yourself and your entire team up without knowing which bit of code you committed years ago caused it.
