I suppose you could say that all OO is just a way to attach a dispatch table to some data structure. However, the other classes are not supposed to need to know what the actual data structure is, since they access it through methods. If you re-bless an object, your code (the part that does the re-blessing and the class you re-bless it into) will now break if the internals of the original class break, even if the API doesn't change.
