I am not saying you are wrong because I do not know Rust but it appears you only consider variables in your case and not cont parameters for methods and cont m

  Good point - by dwelling on variables, I failed respond to the article on the precise topic. Now I'll illustrate const methods and parameters as per your suggestion. Rust: fn reads_myself(&self) { ... } fn writes_myself(&mut self) { ... } fn reads_arg(w: &Widget) { ... } fn writes_arg(w: &mut Widget) { ... } C++: void readsMyself() const { ... } void writesMyself() { ... } void readsArg(const Widget &w) { ... } void writesArg(Widget &w) { ... }

  Rust treats parameters identically to local variables, since they are just local variables. All rules that apply to variables also apply to all function arguments (including `this`/`self`).
