Thank you everyone for giving their attention and thoughts to the thread, especially Yukihiro-san. It's truly an honor. I believe my question has been answered already and discussing advantages and disadvantages of multi-inheritance over single-inheritance with aid of modules is another thing. Hearing everyone's thoughts especially the master, I think I would just accept and respect Ruby the way it is, save that someday I might make a personal extension of it if I'm able, well not really. Thanks again. I actually imagined this: class Ruby inherit Multiple inherit Inheritance end Just my thoughts. Cheers, Ross -- Posted via http://www.ruby-forum.com/.
