They're associations in class pools, and are visible in the instance-side and class-side methods of the class and all its subclasses. See Class>>bindingOf: and Class's inst var classPool. Shared pools are similar. A shared pool stores its variables in its class pool, but other classes can have its class vars in scope by including the shared pool in its pool dictionaries. > If not, how do I get the slots? > Well, just for clarity (at least I hope it'll bring clarity). One can access the variables via MyClass classPool associations Note that these are entirely different from class instance variables, which are inst var slots in the class object. These hold things like the class's superclass, its method dictionary, etc. But one can add inst vars to one's own class. There are many examples of this. Since these slots are per-class every class gets its own copy of the slot, and because these are inst vars, they are only in scope in class-side methods of the defining class and subclasses.
