Does vector<T>::iterator throw if it goes past .end() ? no.
I think boost simply models after the standard.

What I agree it lack is some kind of .count() so you know how much tokens
there is,
but what you can do to get the info is :

       if(std::distance(tok.begin(), tok.end()) < 3)
       {
               std::cout << "not enough arguments\n";
               exit(1);
       }

       arg1=*pos++;
       arg2=*pos++;
       arg3=*pos++;
