Is there a reason not to convert this test to use bound? It looks like into_ref() is the only deprecated piece here.

This explicitly tests the std::error::Error impl, which the Bound api can't implement anymore.

Hmm, do we need to be providing an impl of Error for Bound<'_, T>?
I think I missed this because this PR doesn't (yet?) but that impl behind a cfg, unless I really missed it.

The Error impl does not exist anymore, because we can't implement source() anymore using the Bound API, see #3820 (comment). (It would also be problematic for user defined exceptions, because of orphan rules, but I think we could work around that using a marker trait and blanket impl if we wanted to)
