I was also under that impression. That issue, however, was about Size in algos,
which, at least, is required to be convertible to an integral type. I don't
think we even have such *minimal* requirement here... What do you suggest?
Should the LWG discuss such kind of requirements for Distance too? In the
meanwhile suspend? I have no strong opinions...
