    application: Tie the catch block more tightly to the failure site
    
    Having a lot of code inside a try statement makes it harder to follow
    the error handling logic. The catch statements are far away from the
    code that can throw an exception, so it is difficult to match them
    together. Let's reduce the size of the try blocks by only using them
    for fallible operations.
