Sorry to go a bit off topic, but I find it funny that I never really
noticed you could perform less-than or greater-than comparisons on
Bool values. What's the semantic reasoning behind allowing relative
comparisons on booleans? In what context would you use it?
The Boolean values form a Boolean lattice. That's reason enough.
It seems
to me a throwback to C's somewhat arbitrary assumption that False=0
and True=1.
That's not arbitrary at all. 0 and 1 are very special numbers, because
of the roles they play in addition and multiplication. They "absorb"
and "identify" things.
