No, I'm sorry -- "another language" and a "new version of an existing  
language" are not the same thing. Or do you think ES3 is another  
language from ES2, which came before it? ES3 added new syntax not in  
ES2 (likewise ES2 to ES1).

The world has been through JS evolution before. We'll get through  
another round.
