you're not wrong... Null by itself is sort of crazy in a binary system, but I see that as more a problem with binary representing reality rather than the other way around. It's a handy abstraction in that sense but a nightmare for systems level programming.

The concept is useful, the implementation is not. You really just want better ergonomics for enums, and encode the many ways NULL is meant to mean that way
