    sec-getoption step 10:
      10. If _values_ is not *undefined* and _values_ does not contain an element equal to _value_, throw a *RangeError* exception.
    sec-temporal-totemporaloverflow step 1:
      1. Return ? GetOption(_normalizedOptions_, *"overflow"*, « String », « *"constrain"*, *"reject"* », *"constrain"*).
    sec-temporal-isodatefromfields step 2:
      2. Let _overflow_ be ? ToTemporalOverflow(_options_).
    sec-temporal.calendar.prototype.datefromfields step 6:
      6. Let _result_ be ? ISODateFromFields(_fields_, _options_).
