Or how to tell R CMD BUILD to use a refhook. Unless I misunderstand when refhook comes into play. One example of the kind of thing I'm looking for is in Matlab, where you can have loadobj() or saveobj() methods; if a class has these methods they will be used to mangle objects of that class as they are de/serialized.
