Shouldn't Order::Increase numerify to +1 and Order::Decrease to -1? In
which case it would be clearer to put them in respective order above...
Maybe you could view it either way, although I think going the other
way around would make more sense only if the names were Order::Lower,
::Same, ::Higher.
S03 matches the old cmp semantics in that "3<=>4" returns -1, which
represents increasing order because reading left-to-right, we go from
3 up to 4.
However, what I'm wondering is whether Order::Same is "but true" and
the others "but false"? (Which makes cmp in boolean context the same
as eqv, but it seems to make sense that way.)
