| * The set may contain fewer elements than the iterable, if the iterable |
| * contains an element more than once, or it contains one or more elements that |
| * are equal. The order of the elements in the set is not guaranteed to be the |
| * same as for the iterable. |
| * @description Checks that the returned set is correct. |
