If we’re looking at it from a Rust angle anyway, I think there’s a second reason that OOP often becomes messy, but less so in Rust: Unlimited interior mutability. Rust’s borrow checker may be annoying at times, but it forces you to think about ownership and prevents you from stuffing statefulness where it shouldn’t be.
To be fair, that's an issue in almost every imperative language and even some functional languages. Rust, C, and C++ are the only imperative languages I know of that make a serious effort to restrict mutability.
How do C and C++ try to restrict mutability?
constThey don't do it well, but an attempt was made.
