I was wondering what kind of constants this would include. Physical constants, or just mathematical ones? And what about constants with multiple expressions depending on units? For example, H_bar = 6.626e-34 J-s = 4.135e-15 eV-s.
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?
