While review tend to be very thorough, it is sometimes hard to spot when we

How the BUG/ASSERT_UNREACHABLE solution is going to help us here?
I understand that hitting -Wswitch requires less efforts, the compilation only. 
Otherwise build run, even fulfilling some conditions are needed to hit missed 
enum index.

But how those `switch()` without `default:` label are protected against the 
value outside the enum?
