Well, I'll be darned.
var a:Object = new Object();
var b:Object = a;
a.toString = function():String {
return "object";
}
trace(a + ", " + b);
delete a;
trace(a + ", " + b);
Output:
object, object
undefined, object
Is there any difference at all between deleting a variable and setting
it to undefined?
