If it wasn't for the final keyword (doesn't exist in many 
languages!), we could discuss this topic. Am I wrong, using 
`final` removes `default`.

If there is a possibility that the `switch` value may not match 
any of the specified cases, you should include a `default` case. 
In this case, you would not use `final switch`, as the 
optimization relies on the assumption that the switch value will 
always match one of the specified cases.

IMO, we should discuss "should the `break` keyword be removed"
