It's a mistake to think of John's range as being a refinement of the
boost.range concept.  If I have a non-const range and I pass it off to
an algorithm that traverses it, will the range be modified or not?
That should not change depending on which level of this "refinement
hierarchy" the algorithm requires, or depending on whether the range
was only non-const by chance (but not really intended to be modified).
