consider this usage:
quantity<SI::length> l1(2.0 * SI::meters);
quantity<SI::length> l2(2.0 * Astro::parsecs); //for illustration only
That's why you need the unit multiplication on the right. This seems to
me to be a very clear way to express the fact that you want the quantity
to be in the SI length unit (which is the meter), but you want to be
free to use whatever units you want to specify it on the right.
