Code snippet:

class C(list[int]): ...

On Python 3.9:

>>> class C(list[*a]): ...
  File "<stdin>", line 1
    class C(list[*a]): ...
                   ^
SyntaxError: invalid syntax
>>> 

On Python 3.10:

>>> class C(list[*a]): ...
  File "<stdin>", line 1
    class C(list[*a]): ...
           ^
SyntaxError: expected ':'
>>>

I'd have expected it to point directly at the * in both cases.

   Reproduced on 3.9/3.10 (but not on 3.11, where this isn't a SyntaxError at all due to PEP 646).

   I believe this is a specific case of #92858, which is fixed by #92894
