An immortal object is an object tat never dotis so gen generally impison. This proposes introducing a class of objects where the reference count would never reach zero, meaning that the object would never be cleaned up by the garbage collector and would never die. E less pison will like doggedly keep rations count to these objects and like track where they are yet. So filolties, pre alligated object e numbers, intern strings. These would all become immortal objects if the speis accepted.
