You cannot even express distinct 1:1 relationships directly as well certain other aspects of real life. My gut feeling tells me, this idea is unlikely to take off. Why should I use a simple model in order to model real world situations which are significantly more complex than the capabilities of the model when I can use a more adequate model? Regards robert
