Is Nil() gone?

Hi and thanks for this library!
I recently found it and wanted to port some existing code to use it.

In the readme, it mentions the evaluation criteria, and that this function was decided to keep:

Nil(t, value) -> frequently used, keep

But, it seems to not be in the repo?

I am using github.com/alecthomas/assert/v2

Maybe I'm just doing it wrong?

EDIT: I see that `assert.NoError(t, err)` does what I want.
