As you mentioned security, would a mechanism for notifying clients of
object/variables replacement be something useful/feasible, say, for
2.0?
Object/function replacement is evidently an asset in JS, but it does 
introduce security issues which are very hard to track down and plug. 
With such callback mechanism, clients would at least be able to decide
which replacements should be allowed to go through.

Great to hear 2.0 is on the move. I was at Waldemar's talk a couple of
weeks ago, and was very impressed with the new possibilities. As he
said:
"better over-design now than be sorry later".
