Dear Martin,
Please look at the first line in the Boost Design and Programming
Guidelines :
http://www.boost.org/more/lib_guide.htm#Guidelines
It may be that some compilers optimize the current code better than
others and that some do very poorly. Also in accordance with the
aforementioned guidelines we have not focused primarily on
performance or performance testing. There is no fundamental reason
why the code should not be able to be optimized away, but achieving
that for many compilers may need to be left for later. It certainly
will never happen without a putative starting point. Finally, if a
nominally compile-time unit system incurs as much overhead as you
seem to believe, imagine the cost of a runtime system...
Cheers,
Matthias
