If you need more complex logic, you simply wouldn't use `try!()`. Try! is intended for those `if error then return` checks, just like with Go's `if err != nil { return err }`.

If the error needs to be checked for a specific type (like a timeout) and then retried X times, you don't use the simple `if err != nil {...}`, you hand write something:

    let barRes = try!(foo()).bar();
    match barRes {
      Err(MyError::Timeout(_)) => // .. some retry code
    }

Note that the above code is woefully incomplete (i'm not checking all possible match values, for example), but it should give you the gist of the idea.

edit: Man, the guy (or wo-guy) has a problem and we all pounce :)
