I'm not sure I understand. Are you saying that Chris's __getitem__ will not be called by other dict methods that would normally call this magic method and instead call the parent's __getitem__ directly (via super() or something similar?)? Is this specific to the native Dict class (because its implemented in C vs. Python?) or is this behavior more general. Malcolm
