[$] Improved error reporting for CPython 3.10—and beyond

In a fast-paced talk at PyCon 2022 in Salt Lake City,
Utah, Pablo Galindo Salgado described some changes he and others have made
to the error reporting for CPython 3.10. He painted a picture of a
rather baffling set of syntax errors reported by earlier interpreter
versions and how they have improved. This work is not done by any means,
he said, and encouraged attendees to get involved in making error reporting
even better in future Python versions.
