I assume you mean by the "null or exception" proposal? I think many 
people have made it quite clear that they think that is the least good 
solution as it doesn't produce interoperability across browsers.

Hehe, yes, that has been quite clear :)

Yes please do, I'm curious as to what those technical arguments are. The 
one I've heard so far is concern about site compatibility with returning 
null. I.e. you guys are concerned that sites will break if an exception 
isn't thrown.

Are there other ones? Do you have any data to back up the compatibility 
concern?
