Expected Behavior
All tests should pass.
Your Environment
- Mypy version used: 0.942
- Python version used: 3.10.3
- Operating system and version: ALTLinux
I think this is due to this change:
https://docs.python.org/3/whatsnew/changelog.html#id3
bpo-46240: Correct the error message for unclosed parentheses when the tokenizer doesn’t reach the end of the source when the error is reported.

For example, Python 3.10.0:
[someuser somedir]$ echo 'public static void main(String[] args)' | python3 -
File "<stdin>", line 1
public static void main(String[] args)
^^^^^^^
SyntaxError: invalid syntax. Perhaps you forgot a comma?and Python 3.10.3:
[someuser somedir]$ echo 'public static void main(String[] args)' | python3 -
File "<stdin>", line 1
public static void main(String[] args)
^^^^^^
SyntaxError: invalid syntax
