Have you considered faking scopes in JS using anonymous functions?

----
var foo;

(function(a, b){
	var foo; // not the same as the foo outside the func!
	// do stuff
}(x, y)); // invoke immediately with needed arguments from outer scope

by passing all the parameters to the anon func you get a speed increase 
in the lookup on most JS platforms.

I don't think they are very pretty, but it is sometimes a useful technique.
