Returns a ConstSet where each value is a Pair that combines the value of the current ConstSet and the provided Traversable

public function zip<Tu>(
  Traversable<Tu> $traversable,
): ConstSet<nothing>;

If the number of values of the current ConstMap are not equal to the number of elements in the Traversable, then only the combined elements up to and including the final element of the one with the least number of elements is included.

Note that some implementations of sets only support certain types of keys (e.g., only int or string values allowed). In that case, this method could thrown an exception since a Pair wouldn't be supported/
