every other language with constants have exactly same behavior, so it’s exactly right and not funny.

The reference to the object BASE is constant and can’t be redefined to point to another Object. It has no effect on the object’s members.

If as3 is like most other languages, this is because any variable of a non-primitive (object) type only stores the reference to the actual object (i.e. the memory address of the object data). So the const is still constant because you cant set the BASE const to point to a different object, as you can with a normal var, such as:

var obj1:Object = {name:’banana’, color:’yellow’};
var obj2:Object = obj1;
obj2.name = ‘apple’;
trace(obj1.name); //output is apple

I thought only numbers, strings etc can be a constant. After giving some more thoughts, I realize a constant object is a constant pointer pointing to something can be changed from time to time.

Actually, I think this makes a lot of sense.

FunnyStaticConst:BASE is a static constant, not it’s members, so of course you should be able to change them. You should not, however be allowed to redefine FunnyStaticConst:BASE altogether (such as FunnyStaticConst:BASE = {who:’me’, when:’now’}).

It’s really funny !

Object is a dynamic class, so its properties can be added at run time. May be this situation happens to any other dynamic classes as well. Let’s try it on.
