Thanks Ovanes - I'm sure you will understand that my real code is a bit more
complicated then doubling ints! Since both bind and lambda are pretty much
superceded by phoenix now, perhaps you could also supply the phoenix version?

As far as I know boost::phoenix is not an officially released boost lib. It is still part of boost::spirit library. There is no top level reference to it. So I would not consider it for now to be a replacement for bind and lambda. It might become, but don't rely on that. ;) Anyway here the rewritten example:

#include <boost/spirit/home/phoenix/core.hpp>

#include <boost/spirit/home/phoenix/scope.hpp>

#include <boost/spirit/home/phoenix/operator.hpp>

#include <boost/spirit/home/phoenix/function.hpp>

#include <algorithm>

#include <vector>

#include <iterator>

#include <iostream>

using namespace std;

using namespace boost;

using namespace boost::phoenix;

using namespace boost::phoenix::arg_names;

using namespace boost::phoenix::local_names;

namespace ph = boost::phoenix;

int main( )

{

vector< int > v;

// generate vector values

int i=0;

generate_n(back_inserter(v), 100, ++ph::ref(i));

//create the output iterator

ostream_iterator<int> oiter(cout, ",");

copy(v.begin(), v.end(), oiter);

cout << endl;

// double each value in the vector

for_each(v.begin(), v.end(), arg1*=2);

copy(v.begin(), v.end(), oiter);

cout << endl;

}
