[$] The PEP 572 endgame

Over the last few months, it became clear that the battle over PEP 572 would
be consequential; its scale and vehemence was largely unprecedented in the
history of Python.
The announcement by Guido van Rossum that
he was stepping down from his role as benevolent dictator for life (BDFL),
due in part to that battle,
underscored the importance of it. While the Python project charts its course in the wake of his
resignation, it makes sense to catch up on where things stand with this
contentious PEP now that has now been accepted for Python 3.8.
