That seems like a somewhat different case, though. Your approach will help prevent new bugs like this from being introduced, but won&#x27;t help you against existing examples of it in areas you&#x27;re not currently working on. And just because it&#x27;s been around a long time doesn&#x27;t mean it&#x27;s &quot;working.&quot; Goto fail showed that the bugs can be subtle and easily missed for a long time.
