There is no such principle as the Sandwich principle. The principle is
Don't Repeat Yourself(DRY). So if you find yourself writing the same or
similar code over and over again, try to figure out a way to extract the
repeated part into a method. That way you can write the code once in
the method, and then call the method when needed.
