If bool has one bit, wouldn’t that bit be the signed bit?
I.e. true < false

Yes, that's consequent. The signed (2-complement) values go 1 more into negative than positive direction.

So 1 bit: -1..0



On the other hand: Bool goes to a maximum of +/-1, so it could also be [-true, false, true]?

signed bool -> [false, -true]?

This calls for `signed bool`, `long short signed bool`, etc.
