Ah but should this change?  This is not all that different
from rich comparisons!  Shouldn't

    not A<B

give the same result as


(at least for appropriate A, B)?  Of course then

    A>B or A==B

should also give the same result.

Hey, if we're gonna get rich comparisons, let's go all
the way.  But, as you say, you can't do it *now*.
