Probably, the problem with Java's `try-catch` is it's not composable and has an abundance of unchecked exceptions (could mess up `catch` type). In Rust, you could just `?` to short-circuit return or do another chained method call `result.map(...).and_then(...).unwrap_or(...)`.

And more importantly, I don't think there's any JEP trying to improve checked exception handling.
