In the first instance I think we'll stick to well defined non-controvercial
numerical constants, the example you give being a good reason to do so ;-)

*If* we can get agreement on the interface, then a later submission of more
physical constants would seem to be in order - perhaps this would be a good
use for Boost.Units?
