Maybe instead of thinking in terms of tracking data changes you ought think in terms of the actions that may change the data and generate some form of notification that the data has changed. Anything interested in the data structure registers interest (probably by providing a callback sub) and does whatever is appropriate when the notification is fired.

True laziness is hard work
