Numeric variable proxies with embedded unit of measurement.
Infrastructure for a library for variables with a given unit of measurement.
Boost::units? My attempt to use Boost::units for the implementation (or directly) failed because the quantity in that library is bound to a dimension without a prefix modifier, e.g. always represents seconds, while we may need nanoseconds. Having a type representing a time in nanoseconds is not trivial, and having two types for representation of time in nanoseconds and microseconds respectively is plain complicate.
On the converse, that library provides arithmetic which is checked for dimensionality correctness. That is beyond the scope of this set of types.
