description: Fast path for converting other Temporal objects to Temporal.Calendar by reading internal slots
info: |
sec-temporal-totemporalcalendar step 1.b:
b. If _temporalCalendarLike_ has an [[InitializedTemporalDate]], [[InitializedTemporalDateTime]], [[InitializedTemporalMonthDay]], [[InitializedTemporalYearMonth]], or [[InitializedTemporalZonedDateTime]] internal slot, then
i. Return _temporalCalendarLike_.[[Calendar]].
