Noisy warnings only justify false positives if the true positives commonly identify real bugs.\n\nIn this case there seems to be a lot of speculation that the warned case is ambiguous. I don't know either way. I do know that clap already has an `impl Args for ()`, but `args: ()` still fires the warning. Could it be relaxed in that specific case?",
