(This doesn't seem like that much of a radical idea, considering 
that this is the case in functional languages, right?)

One small observation, you don't need to add `break;` before `}`. 
(The compiler doesn't emit warnings on missing `break`, but on 
fall-through, and reaching `}` isn't a fall-through.) Sometimes I 
add a comment explaining why the default case does nothing, 
instead of raising an exception or something like that.
