8964	operator>> missing	pipping@…	Matthias Schabel	"boost/units/io.hpp defines operator<< but not operator>>.

As a result, dimensionful quantities can be written but not read. This is a serious problem.

Why would I want to use Boost::Units in the first place? Because I'd like to enter dimensionful quantities into my
program, then do some calculations, and have it output
dimensionful quantities.

The latter (i.e. output) works. But the former (i.e. input) is restricted to hardcoded parameters in my source file. If I move the data to a config file and try to read it, I face the problem that there is no operator>>."	Feature Requests	new	To Be Determined	units	Boost 1.54.0	Problem
