[Python-ideas] Add a mechanism so that multiple exceptions can be caught using `except E1, E2, E3:`

now that python2.7 is EOL, it might be worth resurrecting this syntax as discussed in https://www.python.org/dev/peps/pep-3100/#id13 eg, python 3.11 could support ``` try: ... except (E1, E2, E3) as e: ... ``` as equivalent to ``` try: ... except E1, E2, E3 as e: ... ``` see
