description: Fast path for converting other Temporal objects to Temporal.Calendar by reading internal slots
info: |
    sec-temporal.now.zoneddatetime step 1:
      1. Return ? SystemZonedDateTime(_temporalTimeZoneLike_, _calendar_).
    sec-temporal-systemzoneddatetime step 3:
      3. Let _calendar_ be ? ToTemporalCalendar(_calendarLike_).
    sec-temporal-totemporalcalendar step 1.a:
      a. If _temporalCalendarLike_ has an [[InitializedTemporalDate]], [[InitializedTemporalDateTime]], [[InitializedTemporalMonthDay]], [[InitializedTemporalYearMonth]], or [[InitializedTemporalZonedDateTime]] internal slot, then
        i. Return _temporalCalendarLike_.[[Calendar]].
