"with" still sucks + removing features + adding features

Yeah, so for the sake of a feature intended to save some minor typing, 
I'm thrilled to introduce a feature requiring me a ton of typing.

Yah.

enum DeviceStatus { ready, busy, fail }
...
void process(DeviceStatus status) {
    final switch (status) {
    case DeviceStatus.ready:
       ...
    case DeviceStatus.busy:
       ...
    case DeviceStatus.fail:
       ...
    }
}

If you then add a new value for DeviceStatus, the final switch won't 
compile.

I think it's important to give switch a crack on properly optimizing its 
code. And case a .. b I just explained to Jarrett.
