Yes, that would probably be good. I don't think it matters in this
case. But seeing we explicitly only use 2bits to hold the state it
might be more clear to be explicit about the unsignedness. I guess,
like clang, I see hex constants as just bits without thinking of them
being constant types with a specific signedness :)
