[boost] Compile-time of unit-libraries

Hi,

I just had an idea and as I still don't have the time to work on a 
unit-library myself, I'd like to share it with the authors of the 
current libraries. I don't know if it's a stupid idea, but anyway:

Compile-time is an issue. What if the library can be put into a check- 
and non-check-mode? During development, I'd use the check-mode to make 
sure that my code is correct. For the release build, I would disable all 
checking as this checking was already done in my debug builds. 
Disableing checking would then not use MPL, all units/dimensions are 
equal and whatever you do it gets accepted. This could possibly safe a 
lot of instantiations, thus both memory and time during the compilation. 
Don't know if it's worth the effort, but as I said, it's just an idea.

Regards, Daniel

PS: Matthias' example idealGasLaw() sent my constant library back to the 
design phase (*sigh*). The main problem is the lack of typeof, even the 
currently available extensions from GCC and the Intel-compiler 
(__typeof__) only give me internal compiler errors :(

PPS: Matthias: Is there a recent version of your library available 
somewhere or is the v2.2 in the files section the most current one?
