Hehe... rather amusing given that morph = change and change = dynamic. So it's redundant to say the least. It'd be neat to see the mentor's (who refuses to answer two simple questions I asked him) example of static polymorphism lol.

Anyhow, it should be obvious to almost anyone who has implemented OOP that, as I said in a previous post:

  ... what JOG had in mind is that hierarchal methods are   often used to /define implementations/ of OO. For example   inheritance and composition.

  Thus the /static/ structures of OO designs are often   hierarchal. The /dynamic/ structure of OO programs can   more generally be a network.
