This is fundamentally incompatible with :
I'm not sure I agree with that rule. And anyway, D's final

I don't see the incompatibility. This is exactly the purpose of
final switch. If the user didn't want to be forced to handle a
new error category, they'd use normal switch instead.
You have yet to specify the problems with switch in OOP. Maybe
