fully agree, distinguishing between torque and energy is artificial. And
just look how much complications it adds to the library! Whole new
concept of anonymous_quantity, serialization (outputting units values)
burden, etc...

Displaying a unit using correct unit should be left up for the user - he
chooses what name he wants displayed. The library could only take care
to correctly convert the value for output requested so that it matches
required unit - eg. passed as a string: "kNm","Nm","J","kWh" or "kg m^2 s^-2"
