AFAICT boost::scoped_array only stores the array as a pointer, hence the
size information is lost and it is not possible to obtain the end of the
conceptual range from this class alone. boost::scoped_array is primarily
intended to work in a similar fashion to boost::scoped_ptr but for
allocations that require a corresponding delete[].

Perhaps consider boost::array, std::string, or std::vector instead?

Yes, there is - boost::make_iterator_range(first, last)
