== Description

Decrement the specified iterator `iter` to refer to the previous element in the referenced array, and return an iterator referring to the original element (_before_ the decrementation). The returned iterator, `it`, referencing an element within a `PackedIntArray`, `array`, remains valid as long as `0 <= it ‐ array.begin() <= array.length()`. The behavior is undefined unless, on entry, `PackedIntArrayConstInterator() != iter` and `0 < iter ‐ array.begin()`.
