IIRC, you are only allowed access to the const interface of items held by 
multi_index containers. Non-const methods by definition mutate the object 
upon which they act, which could change the item's state upon which the sort 
order is based. That is why you must use multi_index's update functions to 
modify the state of any of it's items.
