> [T]here's other optional fields in the ast, type ignores don't seem essential to the `Module`, could those be made optional as well? I think you're referring to the `?` syntax in `Python.asdl`. But the `type_ignores` attribute is already a list (using ``) and AFAICT you cannot combine `?` and ``. You have to provide an empty list.
