Hi All

In this bit of code....

#include <algorithm>
#include <vector>
#include "boost/bind.hpp"

struct A
{
    int double_it( int i ) { return i * 2; }
} a;

std::vector< int > v;

int main( )
{
    for ( std::vector< int >::iterator i = v.begin( ); i != v.end( ); ++ i )
    {
        a.double_it( * i );
    }

    // Write it as a for_each/bind
    std::for_each( v.begin(), v.end(), boost::bind( & A::double_it,
boost::ref( a ), _1 ) );
}

Is that last line the idiomatic way of writing the bind expression?

Thanks, Rob.
