>With Rust one must first train brain to wrap around those ownership rules and this might not be easy.

C++ users already understand ownership because C++ has ownership too. With C++ you have to me extra careful because the compiler won't save you from making mistakes like Rust will.

I meant ownership as implemented in Rust. I am perfectly fine with ownership models of C++ and some other languages.

>I meant ownership as implemented in Rust.

It's the same thing in Rust and C++. There is no difference conceptually.

Disagree, unless we're including Rust's unsafe. Excluding that, you need to understand what the Rust compiler is able to prove is safe. In C++, you "just" need to prove to yourself that it's safe. It's a very different experience writing code.

So perhaps "ownership rules" is the wrong vocable for this. Maybe "ownership proofs"?

In Rust you need to understand borrowing to write programs that compile. In C++ you need to understand borrowing to avoid writing programs that use undefined behaviour.

Yes, it's a different experience, but both have the same concept of borrowing that you must understand.
