    Set ( [ iterable ] )

    When the Set function is called with optional argument iterable the following steps are taken:

    ...
    5. If iterable is not present, let iterable be undefined.
    6. If iterable is either undefined or null, let iter be undefined.
    ...
    8. If iter is undefined, return set.
