now that python2.7 is EOL, it might be worth resurrecting this

eg, python 3.11 could support
```
try:
...
except (E1, E2, E3) as e:

as equivalent to
```
try:
...
except E1, E2, E3 as e:

I think you really mean you want Python to accept the form without the
parenthesis. I don't like it because it's easy to read that as
except E1, E2, (E3 as e):
and I don't think saving two characters is worth the disruption caused
by people being able to write Python 3.11 code that won't work in Python
3.10. Many people would not adopt the new syntax for that reason.
I'm not keen on it either.
On the other hand, binding to e for E3 but not for E1 or E2 would be
kind of weird, and "e = E1, E2, E3" is valid.
On the third hand(!), 'as' is used in the 'import' and 'with'
statements, where it binds to only one preceding item.
