Regardless of whether the objects are targets of "constant references" (whatever that means), programs should not modify the objects in question. And if the semantic point makes no practical difference, why complicate the manual with it? It's simpler just to say: programs shouldn't modify these objects. > The "whole story" can be enumerated in some place, sure.

They're not the only thing to cover, and attempting to shoehorn this all into self-evaluating forms could even be misleading.
