What is the status of ranges in C++?

Sometimes I get tired of all this my_vector.begin(), my_vector.end() noise. Last year at boostcon, Andrei Alexandrescu's keynote speech was titled Iterators Must Go (video)

Is there any progress on introducing ranges into C++, so I can finally say std::sort(my_vector)?

Range in C++ still has an insufficient experience.
As current experimental implementation, there are Boost.Range 2.0 and Oven Range Library.

#include <iostream>
#include <vector>
#include <algorithm>
#include <iterator>

template< class Container >
void sort( Container& c ) { sort( c.begin(), c.end() ); }

int main()
{
    using namespace std;

    int const           data[]  = {3, 1, 4, 1, 5, 9, 2, 6, 5, 4};
    vector<int>         v( data, data + sizeof( data )/sizeof( *data ) );

    sort( v );
    copy( v.begin(), v.end(), ostream_iterator<int>( cout, " " ) );
}

Of course, replace member function calls begin and end with calls of startOf and endOf (your versions), at least until C++0x...

As far as I know, no progress has been made toward that end.
