Braden,
Great work on this. In addition to helping with constraints there is at
least one new library feature that depends on constexpr variable templates.
For my two cents it would be good to get just the constexpr variable
templates, aka n3651, in now as a first stage - it's quite usable.
But someday we'll want non-constexpr too. I have only seen a sentence
somewhere stating that non-constexpr variable templates are allowed but
have seen no paper or wording anywhere. Does anyone know where such exists?
