Earlier on, i noticed this little gem on reddit:

Which led me to this rather interesting mailing list post by Douglas Crockford:

I apologize for my ultrablunt comment. Let me be clear about what I
meant. It was decided at the Oslo meeting that the project formerly
known as ES4 is no more. Instead, there will be a new project,
Harmony, which will be the work of a unified working group. We have
not yet agreed on a set of goals for Harmony.

I recommend that we close the ES4 list and open a harmony list to
support this new effort.

Looks like nobody can agree on any set goals for JavaScript 2 (i.e. ES4). Which leads me to think that as with a lot of web standards, JavaScript 2 is just a pipe dream.

Fortunately though, the real world has a solution which already works. Its called haXe, and it implements a lot of what JavaScript 2 should be.

So instead of waiting about for some standards crackpots trying to cobble together a standard, you can write some real code.

Have fun with haXe.
