Another probably-bug. It seems like dependency resolution fails when you have import blocks that are formatted like this:

from typing import (

    cast,
)

The relevant code uses

tokenize.generate_tokens

to extract imported symbols on each line of the import, which crashes when a line is empty in multi-line statement. Although arguably this is a bug in the tokenize library itself. How unfortunate.

You are maintaining a codebase with all sorts of hidden treasures!

A true natural fuzz test

If you import modules instead of module members, does this go away?

I'm not sure but I would think tokenization doesn't care about the semantics of what each symbol means. That comes much later

File an issue?

Yes please! And link to it here. This seems like a straight up bug.
