`dict` function-based initialization is rejected

The following gives: No overload of bound method `__init__` matches arguments

```python
SESSION_OPTIONS: dict[str, Any] = dict(
    # Allow models to be read after transactions are closed
    expire_on_commit=False,
    # Do not allow implicit re-use of sessions after their context closes
    close_resets_only=False,
)
```
