I cannot figure out how to copy a vector to another vector and calling
a member function. Please consider the following example.
#include <string>
#include <vector>
#include <algorithm>
#include <functional>
#include 
using namespace std;
using namespace boost;
class A
{
public:
  A( const string& name ) : _name( name ) {}
  const string& name() const { return _name; }
private:
  string _name;
};
int _tmain(int argc, _TCHAR* argv[])
{
  vector<A> as;
  as.push_back( A( "A" ));
  as.push_back( A( "B" ));
vector<string> ss;
// how to call A::name for each A????
  copy( as.begin()
      , as.end()
      , back_inserter( ss ));
transform( as.begin()
            , as.end()
            , back_inserter( ss )
            , bind( &A::name, _1 )
            );
...
return 0;
}
I'm sure it's very easy, but I don't see right now.
