Paul touched on a very good sub-topic.  Just as the `goto case` 
protects us (this was added recently)), the `default` and the 
`final` duo allow us to choose.  Therefore, if there is a 
`final`, there should be no `break` and `goto case`.

I think 2 modes are enough:
* final and switch
* switch and default
