Actually, we could just use pointer() everywhere, which would work today and
would be equivalent to using nullptr, assuming the current proposed resolution
of 834 or something similar.  I would be very surprised if 834 is resolved in a
way that allows different semantics for get() == nullptr and get() == pointer()

i.e.

      explicit operator bool() const
      { return get() == pointer() ? false : true; }

      // Modifiers.
      pointer
      release()
      {
        pointer __p = get();
        std::get<0>(_M_t) = pointer();
        return __p;
      }
