>>Who doesn't go into the implementation with the solution worked out? OOP, as Allan Kay envisioned it, is about making developing software a process of learning about what you are modeling. You are expected to naturally find the solution to your problem as you model it, not to have a worked up a solution you have to put into the code. With real-world sized problem, this approach gives good results. But, obviously, it can fail to find some great solutions. As is the case for the Hanoi problem: you can model it very well without finding the optimal solution to it. But the model still has some added usefulness.
