Backport of the pickle 5 protocol (PEP 574)

==========================================================
pickle5 -- A backport of the pickle 5 protocol (PEP 574)

This package backports all features and APIs added in the pickle module
in Python 3.8.3, including the
PEP 574 <https://www.python.org/dev/peps/pep-0574/>_ additions. It should
work with Python 3.5, 3.6 and 3.7.

Basic usage is similar to the pickle module, except that the module
to be imported is pickle5:

.. code-block:: python

import pickle5 as pickle

pb = pickle.PickleBuffer(b"foo")
data = pickle.dumps(pb, protocol=5)
assert pickle.loads(data) == b"foo"

Detailed documentation can be found in PEP 574 and the standard
pickle documentation <https://docs.python.org/3.8/library/pickle.html>_.
