Hi,

What sort of magic do I have to write to get this sort of thing to work?

===
typedef boost::units::quantity<boost::units::si::length> length_t;

length_t earth_radius = 3438.461 * nautical_mile;
===

boost::units defines a boost::units::metric::nautical_mile_base_unit in terms 
of meters, so the numbers and concepts are in the library already. Somehow. 

Thanks for any help :)
