What is a de facto standard exactly? The fact that '__proto__' allows to
get and set the prototype? This basic definition stands, but I have
heard of bugs: https://bugzilla.mozilla.org/show_bug.cgi?id=690027
Firefox 7 recently added a '__proto__' property to Object.prototype
(https://bugzilla.mozilla.org/show_bug.cgi?id=690031). Would it be part
of the non-mandatory spec?
Making __proto__ part of the spec sounds like an incitation to authors
to use it. I agree that implementors should agree for interoperability
purposes, but I'm not sure the official ECMAScript standard is the right
place to do so since it is intended for authors as well.
