.. section: Library
``_abc`` module is added. It is a speedup module with C implementations for
various functions and methods in ``abc``. Creating an ABC subclass and
calling ``isinstance`` or ``issubclass`` with an ABC subclass are up to 1.5x
faster. In addition, this makes Python start-up up to 10% faster.
Note that the new implementation hides internal registry and caches,
previously accessible via private attributes ``_abc_registry``,
``_abc_cache``, and ``_abc_negative_cache``. There are three debugging
helper methods that can be used instead ``_dump_registry``,
``_abc_registry_clear``, and ``_abc_caches_clear``.

``_abc`` module is added. It is a speedup module with C implementations for
various functions and methods in ``abc``. Creating an ABC subclass and calling
``isinstance`` or ``issubclass`` with an ABC subclass are up to 1.5x faster.
In addition, this makes Python start-up up to 10% faster.
Note that the new implementation hides internal registry and caches, previously
accessible via private attributes ``_abc_registry``, ``_abc_cache``, and
``_abc_negative_cache``. There are three debugging helper methods that can be
used instead ``_dump_registry``, ``_abc_registry_clear``, and
``_abc_caches_clear``.
