Dear contributors I would like to stress a key difference that some of you may have skipped. class is not equivalent to classSide. class jumps one level while clasSide arrives always to the same level the class. "Point class >>> Point classâ "Point class class >>> Metaclass" "Point classSide >>> Point class" "Point class classSide >>> Point class" So please consider that it is better to use the correct one.
