This is a reasonable request, and one that I had already considered.  It
would require maintaining a whole second header, so I'm not sure it's worth
it. :)  I don't think this would grow the library too much, but I do want
to carefully consider what a range_facade could and should do.  I already
know the answer for iterator_facade.  IOW, I'll probably get to it, if/when
that consideration is fruitful.

Agreed!
