Yes  the dimensional analysis is in practise simple and well known , (due to 
Walter Brown, David Abrahams/AlexeiGurtovoys  et al's code) and could 
presumably be finalised, but it needs implementation of a compile time 
rational eg boost::mpl::rational_c ( I think Cromwell Enage is working on 
this?),  (with some compiletime operators.),which is a 'building block' for 
it.

I assume that the rational impl could then plug straight in to the mpl book 
code ?
