Traversable arguments for container constructors and methods, wording revision 4

by Jeffrey Yasskin

Excerpt:

The STL brought the notion of a range to C++, expressed as a pair of iterators. C++11 added the range-based for loop, which iterates over a single object for which begin(x) and end(x) return that pair of iterators. The Boost.Range library extends this to a full library of algorithms based on ranges as single objects. We don't yet know the full design of the library we want to standardize, but a simple step we already know is needed is to allow the output of that library to be passed to existing functions in the standard library that already take an iterator-pair range.
