PEP654 introduced exception groups and except* in python3.11
Link: https://peps.python.org/pep-0654/

Right now it is possible to parse except* with older ast.parse(..., feature_version=(3, 10)).
Example:

>>> import ast >>> code = ''' ... try: ... ... ... except* Exception: ... ... ... ''' >>> >>> ast.parse(code) <ast.Module object at 0x10c685410> >>> ast.parse(code, feature_version=(3, 8)) <ast.Module object at 0x10c685280> >>> 

Which is not correct.

But, unlike #96427 it is very simple to fix. And I belive it should be fixed.

I've already applied a patch and will send it shortly after :)
