That’s what the ? syntactic sugar is meant to solve. It will return at the point with an Option null, or the error variant of Result if the preceding expression’s error can be converted to it.

something.map_err(…)? is quite readable in my opinion and that is the worst case, when your method returns a Result<..,..> but the called method has an Optional return type. Otherwise it is just a single ?.

Sure, I do believe that exceptions are superior but we do have to understand that rust is a low-level language, period. It is very expressive considering its nature, but it will never be as productive as a managed language in my opinion - we have this distinction for a very good reason. If you want maximal control over what happens “behind the scenes” you loose some automatism that could improve productivity.
