Can't figure out the proper sintax for binding <<. 

class A
{
public:
 friend std::ostream& operator << (std::ostream& stream, A& a);
};

class B : boost::ptr_vector<A>
{
public:
 friend std::ostream& operator << (std::ostream& stream, B& b);
}

std::ostream& operator << (std::ostream& stream, B& b)
{
  std::for_each(begin(), 
                end(), 
                boost::bind(&operator<<, ref(stream), ref(_1)); ???
  return stream;
}
