I still think that a physical quantities library is *very* important. 
Maybe what I would like best would be Andy Little's library just for 
physical quantities, and Matthias Shabel's solution, without predefined 
physical dimensions and units, for the more common needs, and for the 
two to be inter-operable.  I'll tell you why:  for physical quantities I 
like Andy Little's rigor; --I don't even want to be able to mess with it 
to add a "thoughts-per-eye-blink" dimension. Physical quantities should 
be physical quantities. And if I do need thoughs/eye-blink I want this 
to be very obviously under a different mind-space. And yet, if I need 
thoughts per eye-blink per mili-Henry, I'd like to be able to glancingly 
reference the physical quantities library...
