What about the GNU runtime? Is it okay to inspect a Class' +`methods' member (see objc.h and objc-api.h) and change the IMPs that +the individual members point to? Is it possible to add new methods at +runtime by using class_add_method_list and thus +ObjcUtilities_register_method_list? Is the behaviour of these two +functions specified if a method list for a given class has already been +registered in the past? If so, do they replace the original list or +amend it? + +Changing ivars after class creation seems generally impossible. This +applies to all the supported runtimes, and I think I can actually see +why.
