Hi,

I would like to use a for_each with a class member function. 

The for_each in myclass::do_print below does not compile. And I 
simply cant figure it out.

I'm using vc7.1.

////////////////////////////////
void print2(std::string s) 
{
  cout << s << '\n';
}

class myclass
{
public:
  void print(std::string s);
  void do_print();
};

void myclass::print(std::string s) 
{
  cout << s << '\n';
}

void myclass::do_print()
{
  vector<std::string> v;
  v.push_back("a");
  v.push_back("b");
  v.push_back("c");
  v.push_back("d");
  
  for_each(v.begin(), v.end(), 
           boost::bind(boost::type<void>(), 
           &myclass::print, _1));
}
/////////////////////////////////////////

nor will

for_each(v.begin(), v.end(), boost::bind(&myclass::print, _1));
for_each(v.begin(), v.end(), boost::bind(print, _1));

whereas

for_each(v.begin(), v.end(), boost::bind(print2, _1));

is ok

It seems natural to do, but I cant get it.
