I have some doubt about weak references at eventListener. When I add a eventListener with weak reference true, the object don't get a "point/reference" to it but what happens with eventListener array after removing this object. This array don't has the reference for garbage collect, so the garbage collect could collect it, but this object was never removed from this eventListner array, wasn't it? That's my question. Is this object removed from eventlistener array when weak reference is true? Is it feasible to implement it in pure action script or It is a voodoo feature for compiler?
