Hi David,
running function in different scopes only changes the "this" value in the
function. In JS world, you would similarly do:
var myFunc = function() {}
myFunc();
myFunc.call(someOtherContextObject);
However, variables declared in function with "var" keyword are always local
to the function - and global if executed outside any function declaration.
In other words: if you want to use "var x = ..." and be able to choose where
will the "x" property be created, you are out of luck (imho). But if you
change your function to "this.x = ...", you can switch the context object as
necessary.
