Agreed - I thought this looked pretty reasonable, if a bit parenthesis-heavy, until I saw this example:

    func printSum(a, b string) error {
        fmt.Println(
                "result:",
                try(strconv.Atoi(a)) + try(strconv.Atoi(b)),
        )
        return nil
    }

When you nest the calls to try inside another method call, like this, the control flow really becomes obscured.
