Input Iterators vs. Input Ranges

by Eric Niebler

From the article:

The solution to istream_iterator's woes will be to replace it with istream_range. Put simply, if we’re reading strings from a stream, the string needs to live somewhere. The iterator seemed like the logical place when we were all thinking strictly in terms of iterators. But with ranges, we now have a much better place to put it: in the range object.
