Represents a range of slots, where each slot is either vacant or occupied by an integer whose value corresponds to the slot position, taken zero-relative.
The idea is to start with an initial instance whose slots are all vacant, then to add items in at some vacant slot without knowing the exact slot position; instead we specify the vacant slot's index wrt the rest of the vacant slots without caring about the ones already filled.
