BoxSetEach
Invoke a callback for every element of a Set.
The callback receives the element value, its 1-based ordinal position, and the Set itself; single-argument callbacks receive only the value. Iteration follows the natural order of the underlying variant. Use setMap() if you need a transformed result.
