Yep.  It's slow to compile.  I'd love to start a dialogue on  
performance issues as optimizing metaprogramming compile times is about  
as far from my domain of expertise as it gets...

Nope - the dimensional analysis part is completely unit system  
independent.  For all intents and purposes, the SI/CGS/etc... unit  
systems are just applications of the core library for dimensioned  
quantities.
