I suppose that it would also be possible to use only the object, and use decltype whenever you need a type.

I tried using the decltype to get the type but got an error. Is this how you meant to use it?

typedef metric::nautical_mile_base_unit::unit_type nautical_mile_unit; static const nautical_mile_unit nautical_mile;

quantity(2.3 * nautical_mile);

Yes, that's what I meant, but now that I see it written out, it's wrong because decltype keeps the const qualifier. You need the behavior of the non-standard typeof operator. BOOST_TYPEOF should work. In Christ, Steven Watanabe
