The generated operators are functions at namespace scope and thus not any
more associated with one operand than they are with another. Seriously. The
only difference between T and U is that if one is a "more-expressive" type,
you usually want that to be T, since T op U => T.

I'm lost.


P.S. I know it's well-intentioned, but if you forward me duplicate copies of
what you post to the list I have twice as much mail to read and if I reply
to the wrong one it goes only to you... so if it's no trouble, please just
post the discussion to boost.
