bpo-42536: GC track recycled tuples (GH-23623) (GH-23652)
Several built-in and standard library types now ensure that their internal result tuples are always tracked by the garbage collector:
- collections.OrderedDict.items
- dict.items
- enumerate
- functools.reduce
- itertools.combinations
- itertools.combinations_with_replacement
- itertools.permutations
- itertools.product
- itertools.zip_longest
- zip
Previously, they could have become untracked by a prior garbage collection.
(cherry picked from commit 226a012d1cd61f42ecd3056c554922f359a1a35d)
