You could model it like this: every class has a list of included modules which is initially empty. Every time a module is included which is not included in this class or any super class it is prepended to the list. Method lookup starts with the class itself, then proceeds through the list of modules of this class and then proceeds in the same way in the superclass; the process is stopped when the first matching method is found. If not matching method is found the lookup process starts again with name "method_missing". (That process with end in class BasicObject which has a definition of #method_missing.) > Any MRI experts -- how does it _really_ happen? > And how about JRuby/Rubinius? You can look it up in the implementation - it's OSS.
