8.2.2.3 Tuple.of ( ...items )
The of method takes any number of arguments, and performs the following steps:

1. Let items be the List of arguments passed to this function.
2. For each element e of items,
a. If Type(e) is Object, throw a TypeError exception.
3. Let tuple be a new Tuple value whose [[Sequence]] is items.
4. Return tuple.
