Any methods it does not understand will be delegated to the object at the bottom of the stack (the far end of the chain),

Objects of this class consist of a reference to an array, the elements of which are the objects in the chain (the first element being the global object). (Think of it as a stack.)

$scope-> if no call object is found.
Just bless an array reference.
