  Yes, exactly. It is the Rust equivalent of goto.

    Goto is bad because it results in very difficult to reason about code. Using unwrap and expect is as bad as using any other language without null safety.

      goto is bad when it's used in a way that makes it difficult to reason about code, but not all uses of goto are like that. The usual C pattern of `if (err) goto cleanup_resources_and_return_err;` is a good example of the use of goto that is not difficult to reason about. Using unwrap/expect is still much better than using a language without null safety because unwrap/expect make it immediately obvious at which point a panic can occur, and creates some friction for the dev writing the code that makes them less likely to use it literally everywhere.
