Thanks for the examples.
I would like `nonstop` and `generation` as well to be included in
OvenToBoost!

One question about implementation of `single`:

  template <class T>
  inline iterator_range<const T*> single(const T& x)
  {
      return make_iterator_range(boost::addressof(x), boost::addressof(x) + 1);
  }

I'm concerned about taking one-past-the-end pointer of non-array object.
Is this guaranteed to work?
If so, could you tell me which part of the Standard guarantee it?
