description: Fast path for converting other Temporal objects to Temporal.Calendar by reading internal slots
info: |
    sec-temporal.plaindate.prototype.equals step 3:
      3. Set _other_ to ? ToTemporalDate(_other_).
    sec-temporal-totemporaldate step 2.c:
      c. Let _calendar_ be ? GetTemporalCalendarWithISODefault(_item_).
    sec-temporal-gettemporalcalendarwithisodefault step 2:
      2. Return ? ToTemporalCalendarWithISODefault(_calendar_).
    sec-temporal-totemporalcalendarwithisodefault step 2:
      3. Return ? ToTemporalCalendar(_temporalCalendarLike_).
    sec-temporal-totemporalcalendar step 1.a:
      a. If _temporalCalendarLike_ has an [[InitializedTemporalDate]], [[InitializedTemporalDateTime]], [[InitializedTemporalMonthDay]], [[InitializedTemporalYearMonth]], or [[InitializedTemporalZonedDateTime]] internal slot, then
        i. Return _temporalCalendarLike_.[[Calendar]].
