Sorry, my browser bias is showing.

Sure, E4X is in Flash. Interoperating with itself. Same goes for  
SpiderMonkey. It's not part of the cross-browser standards that are  
implemented in standards, and Michael suggesting that not  
standardizing E4X in ES4 somehow "breaks the Web" is frankly too much.

Now that we've reconnected to Michael's original message and (I hope)  
dealt with the "break the Web" non-threat, are you concerned about  
E4X not being in ES4 for some other reason?
