"""Backward-compatibility shim for unpickling Version objects serialized before
packaging 26.1.

Old pickles reference ``packaging._structures.InfinityType`` and
``packaging._structures.NegativeInfinityType``.  This module provides minimal
stand-in classes so that ``pickle.loads()`` can resolve those references.
The deserialized objects are not used for comparisons — ``Version.__setstate__``
discards the stale ``_key`` cache and recomputes it from the core version fields.
