[Boost-users] boost::cref behavior

Hi all,
 I was trying to understand the use of boost::ref and boost::cref  and
wrote this little snippet:

#include <iostream>
#include <boost/ref.hpp>
#include <string>
using namespace std;

int main(int argc,char** argv)
{
    boost::reference_wrapper<string const> ref=boost::cref(string("yoh"));
    const string das("bla");
    const string & dasref=das;
    cout<<"das ref is "<<dasref<<endl;
    cout<<"ref is "<<ref.get()<<endl;
    return 0;

}

I am confused by what I get when I run this:

das ref is bla
ref is bla

I was expecting:
das ref is bla
ref is yoh

What am I doing wrong there ??
