Mike was getting OT onto the specifics and merits of sandboxed natives/FuseJS.
I was originally answering Allen's prompt for examples of other non
Array uses for __proto__.

Non that provide the flexibility of extending prototypes of natives
directly without the risk of conflict and none
that **work** in browsers/environments from Safari 2.0.0 through IE9.

Thanks for the `hacks` comment.

I and others find __proto__ useful and gave a good use-case as prompted.
I am ok with __proto__'s eventual removal but as you stated earlier
there should be a replacement for use-cases.
The __proto__ property **is** a de facto standard and should be
standardized in some form to ensure compatibility, consistency, and
As mentioned before Array.create() is not enough, something like
Object.subclass() as previously proposed would be flexible for most
eliminate some of the perf/security concerns implementers have.
