description: Type conversions for overflow option
info: |
    sec-getoption step 9.a:
      a. Set _value_ to ? ToString(_value_).
    sec-temporal-totemporaloverflow step 1:
      1. Return ? GetOption(_normalizedOptions_, *"overflow"*, « String », « *"constrain"*, *"reject"* », *"constrain"*).
    sec-temporal.calendar.prototype.dateadd step 7:
      7. Let _overflow_ be ? ToTemporalOverflow(_options_).
    sec-temporal-addzoneddatetime step 6:
      6. Let _addedDate_ be ? CalendarDateAdd(_calendar_, _datePart_, _dateDuration_, _options_).
    sec-temporal.zoneddatetime.prototype.subtract step 7:
      7. Let _epochNanoseconds_ be ? AddZonedDateTime(_zonedDateTime_.[[Nanoseconds]], _timeZone_, _calendar_, −_duration_.[[Years]], −_duration_.[[Months]], −_duration_.[[Weeks]], −_duration_.[[Days]], −_duration_.[[Hours]], −_duration_.[[Minutes]], −_duration_.[[Seconds]], −_duration_.[[Milliseconds]], −_duration_.[[Microseconds]], −_duration_.[[Nanoseconds]], _options_).
