Can operator= assign const member?

[n.marler]

Class A {
public:
  A& operator=(const A& rhs);
private:
  const int i;
  int j;
};

A& A::operator=(const A& rhs) {
  j = rhs.j;  // this is OK
  i = rhs.i;  // compiler error! how can I make this work?
}

// Not shown: operator= will check for assignment to self
// and return *this, like all good assignment operators.

Thanks for any help!
