Wow, it works! Thanks a lot for the good idea. 
It is cool to write, test, debug and maintain POP codes, while realizing the OOP power.
I think inheritance might be simulated with:
from parentModule import *
I really expect for the day when operator overloading and new-style class features find their way into module.
Thans again.
