Without having perused either Boost::Range or Boost::RangeEx, I think
it's customary to give named access to the underlying iterator type,
just like containers e.g. define iterator, size_type etc.

Oh, I see (s/(end)/(rng)/ I guess). That makes sense.

Perfect. But for ranges to catch up, I guess an easier to spell name
would be in order...
