--- Comment #1 from RazvanN <razvan.nitu1...@gmail.com> ---
Using `back` when `element` is aliased leads to an ice:

  class AssignableRange
  {
      int element;
      int front()
      {
          return element;
      }
      alias back = front;

      void front(int newValue)
      {
          element = newValue;
      }
      alias back = element;
  }

  void main()
  {
      AssignableRange a = new AssignableRange();

      a.back;                                                                   
  }
