Looks pretty good to me. The only question I have is on this part:

enum YesNo : bool { no, yes } // Existing implementation: OK
                               // After stage 1: Deprecation warning
                               // After stage 2: Error
                               // Remedy: `enum YesNo : bool { no = 
false, yes = true }`

Why is this necessary? I can't see how there are integer literals being 
used here, or how implicitly going from `false` to `true` in the 2 items 
being enumerated is going to be confusing.
