Ticket #6521 requests adding:

       class directory{            path p_;            public:                inline directory(path p):p_(p){}                directory_iterator begin(){                    return directory_iterator(p_);                }                directory_iterator end(){                    return directory_iterator();                }        };

so that that a range-based for loop can be used:

    for (auto itr : directory("."))     {         cout << itr.path() << endl;     }

The above works as expected on GCC 4.6 and VC++ 11 beta.

Is that the best way for filesystem directory iteration to support range-based for?

Ticket #5896, Range directory iterators, suggests basing a solution on boost::iterator_range<bfs::directory_iterator>, and that's an obvious alternative to explore. --Beman
