Sorry if I offended you Mr. Little. Your unit library is a fine contribution to boost. I just pointed out the torque / work unit problem because it is a common area in which the proper units often get confused. At some point it would be a useful refinement to an already useful library if it were to support cases like this in which two different units reduce to the same fundamental units but which represent entirely different physical phenomena.

Sorry my lib doesnt quite manage to eliminate the programmer.
