It's not perfect, indeed.

But I want debug-on-error to be t, so setting debug-on-signal non-nil is
not an option because it's too invasive.

Another option would be to declare that the `cl-assertion-failed` signal
does not have `error` as its parent, so ignore-errors wouldn't catch it.
But really, this should only be the case when debug-on-error is non-nil,
which is rather problematic.
