It's nice to see that there appears to be a move in the direction of separating the dimensional analysis and units into orthogonal bits, though. It's the way I've gone... :-)
More than that - I believe its the only way something like this (which is really needed) is going to get into boost at all. I think that it would be best to start with a dimensional analysis library and not worry about units at all until latter. I subsequent units library - there might be several would be built as "users" of the dimensional analysis library. This way, there would be a lot less to try to agree upon. layer 1 dimensional analysis core layer 2 specific dimension systems - usages of the above library - probably more than one layer 3 units core - extension of dimensional analysis library layer 4 specifice units systems. Now I know from experience that lots of people will find say - "if it doesn't include xyz... its just useless". Well, those people are wrong. If sufficient number of people find the lower levels useful, it can accepted eventhough not eveyone wants to use it. Also it would make the library(ies) much easier to understand and use. Robert Ramey
