Since the final switch does not allow a 'default' case, the check can be 
omitted, and the generated code is a simple index-jump, just like the computed 
goto example.

dmd currently doesn't do that, but that's not the language's fault, it's a 
quality of implementation issue.

The point is, computed goto offers nothing that final switch doesn't.
