Hi All

Does the Boost.Range library support initializer_list as a range type? I
thought anything with begin() and end() methods was fair game, but this
code doesn't work, unless I'm doing it wrong.

#include <iostream>
#include <vector>
#include <boost/range/adaptor/reversed.hpp>

int main( )
{
  using namespace std;
  using namespace boost::adaptors;

  vector<int> v { 1, 2, 3 };
  for( int i : v           | reversed ) { cout << i << " "; } // Ok
  for( int i : { 1, 2, 3 } | reversed ) { cout << i << " "; } // Bad
}

Kind Regards

Rob.
