Exceptional Situations in Javascript

[Brendan Eich]

That ship sailed with Edition 3, sorry. The Java precedent weighed  
heavily on TG1 and we have never revisited. I wasn't involved much in  
ES3 (1998, mozilla.org creation), but I remember that we knew about  
the alternative approach, both from Lisp and from some ex-PARC Mesa  
folks at Netscape at the time. Shaver may remember more.

Apart from the history, we haven't heard this request enough to pull  
our focus. Apart from TG1, the idea comes up in the context of  
debugger design, where it can be addressed outside of the language.
