class qualified_scoped_ptr {
          T * operator -> ()       throw() { return p; }
    const T * operator -> () const throw() { return p; }
}
class scoped_ptr {
    T * operator -> () const throw() { return p; }
}

class X {
    void f();
};

some_function()
{
    const           scoped_ptr<X>  spx;
    const qualified_scoped_ptr<X> qspx;

     spx->f(); // OK
    qspx->f(); // compile error (or warning) : non-const method on const object.
}

does that answer your question?
