I guess so, but the 2nd usage will need qualification. Koenig lookup can't
help you there.

I just had a kooky idea. We could get Koenig lookup to work even on
broken-a**ed platforms like MSVC if we used operator overloading.

what if you wrote:

    point p3 = point() << p2;

This is a 'fill' operator. Is this usage just too darned idiomatic and
strange?
