Hi All

I've asked a similar question before, but I can't seem to locate the mail or
recall the
answer! In the code below, how can I eliminate f()?

#include "boost/iterator/counting_iterator.hpp"
#include "boost/bind.hpp"
#include <iostream>

using namespace std;
using namespace boost;

ostream & f( ostream & s, int i ) { return s << i; }

int main( )
{
  for_each(
      make_counting_iterator( 0 ),
      make_counting_iterator( 10 ),
      bind( & f, ref( cout ), _1 ) );
}

If I write something like

      bind( static_cast< ostream & ( * )( ostream &, int ) >( operator << ),
ref( cout ), _1 )

the compiler can't locate operator<<()

Any thoughts, solutions even?

Thanks,

- Rob.
