I have no problem with whatever modelling technique the 
programmer want to choose.

What I hate to see is: if a language does provide the OO 
mechanism, but having some loop-holes that causes trouble for the 
programmer who choose to use it. Esp. when these loop-holes are 
crept in after the language's initial design.

(For example, I won't discuss multiple inheritance on a C forum, 
it's not that language designed for.)
