 Note: Thanks, Ian Keen and Zev Eisenberg and Sven Weidauer
 
 Zev Eisenberg: "Do you still have to specify 1 << _n_ manually for `OptionSet` conformance? There’s no magic?"
 
 This solution creates values that don't matter. They're simply  unique, since option sets should not be accessed by raw value outside the implementation. (Versus direct `UInt`, which supports bit manipulation operations)
