* Several standard library modules have had their import times significantly
improved. The improved modules include :mod:`typing`, :mod:`importlib.metadata`,
:mod:`email.utils`, :mod:`functools` and :mod:`enum`.
improved. For example, the import time of the :mod:`typing` module has been
reduced by around a third by removing dependencies on :mod:`re` and
:mod:`contextlib`. Other modules to enjoy import-time speedups include
:mod:`importlib.metadata`, :mod:`threading`, :mod:`enum`, :mod:`functools`
and :mod:`email.utils`.
