2) Object.prototype.__proto__ is moved back to Annex B.
Since __proto__, unlike __defineGetter__, provides functionality
that is otherwise unavailable, all JS platforms will treat it as
mandatory whether we put it into Appendix B or the main text. At
this point, I think moving this back to Appendix B would be an
obviously meaningless gesture
My "since" is incorrect, as the functionality is available via
Object.setPrototypeOf. Nevertheless, I still think this would be a
meaningless gesture. OTOH, since it is meaningless, it is also mostly
harmless.
Having __proto__ in the main spec be a special form when used as a
property name in an object literal, but relegating
Object.prototype.__proto__ to Annex B, seems inconsistent just on that
basis, too. One place or the other -- main spec or Annex B -- but not both.
