Unrecoverable exception thrown when parsing when parsing a module

[daskol]

Here is a source file which causes the issue.

# datasets/__init__.py
from .dataset import batched3, load_dataset, sample_negatives

__all__ = ('batched3', 'load_dataset', 'sample_negatives')

Here is a pre-commit configuration file (if one omits args then everything is fine).

# .pre-commit-config.yaml
repos:
  - repo: https://github.com/pycqa/isort
    rev: 5.13.2
    hooks:
      - id: isort
        args: ['-c']

Here is a stack trace produced by pre-commit hook.

ERROR: Unrecoverable exception thrown when parsing dataset/__init__.py! This should NEVER happen.
