A good suggestion, we do need to tighten up the tests in that area. I'm also
going to fix the distance implementation so that both ::type and ::value are
sure to work, even in the absence of a ::value in the _impl type. Similarly
for size. That will give Fusion the same convenience as MPL.

It might be a couple of days before I get a chance for that one though.
