To be more precise, [[] for _ in range(10000)] will not effort this patch because range(10000) does not create longrangeiter object.
This patch will affect to if the number is veeery large.

On the other hand, GH-22479 is affect to all index API() whether the number is large or small.

p.s by the way, Naoki is the last name or first name? ;)
