[Meta] Object.{enumerableKeys,enumerableValues,enumerableEntries}

[leobalter]

There's a feature I'm planning to propose to TC39 on the next meeting.

You can check it here with a rationale, use cases, examples and an initial spec.

The name is still in a bikeshedding process and the best alternative candidate so far is Object.enumerableKeys, etc.

Every feedback there is important, thanks!

I'll present this proposal on the TC39 meeting next week, hopefully moving it to stage 1.

The names were finally defined as Object.enumerableKeys, Object.enumerableValues, and Object.enumerableEntries.

This is now marked as my first official rejection from TC39 :)

Making it based in the for...in loop was the main trouble as it also can be easily implemented through an external API.

Let's see if I can reintroduce this without using a for-in or any similar semi-broken behaviour. For now this is not going to survive.
