This is a false positive

I saw this, but I have no clue how we're meant to even start to try to parse such code in practice 😅

I feel it's fine, it still gives people some sense of what's happening.

Yea... idk. I just feel like the suggestion doesn't help. But maybe it's better than without it?

I can always special case it, but the previous error wasn't much better, tbqh
