This is the power of designing before you code. Nothing to do with data structures. Data structures are part of the design but you're focusing on the object o

  You know, I put in a caveat anticipating this objection, but since you raised it, let me offer the following counterpoint: You could implement the approach I described in a language without any OO support, and still come out ahead. Just do it in plain C using function pointers for methods, and write your own dispatcher. Or, do it in assembly (I implemented this approach in PDP-11 assembly). If you do it this way, it really is all about the data structure -- the methods are subordinate to the data structure, acting just like other state. You could even change the methods after objects have been created -- for example, swap in the "evasive maneuver" move method once you fire on an alien ship, so that the alien goes from lazy drifting to taking evasive action.
