I don't disagree with that. However, I'll refer you back to a recent post by Fredrick who re-invented dynamic dispatch within a database language so that he could appropriately decouple the payroll application. The point is that if you treat the data as instructions, then you will eventually come of with the notion of pointers or references to those instructions. From there it's a short hop to dynamic polymorphism, which leads right back to objects.
