Scans the elements in the set sequentially.

When the iterator is used for the first time, it scans all the elements in the set. This operator returns the iterator, which converts to a Boolean type. Once the set has been entirely scanned, the iterator converts to IlsFalse.

The scanning order may change completely as new objects are added to the set or removed from the set.
