I&#x27;ll be thrilled when Herb finally releases his lifetime enforcement tool, but until then it&#x27;s too soon to celebrate. The mystery surrounding the details of Herb&#x27;s approach still raises unanswered questions regarding the soundness and practicality of such a tool.<p>It&#x27;s also evident that Herb didn&#x27;t bother trying to learn from Rust in the slightest back when devising this tool, see his own remarks on Reddit: <a href="https:&#x2F;&#x2F;www.reddit.com&#x2F;r&#x2F;cpp&#x2F;comments&#x2F;3m0d41&#x2F;writing_good_c14_by_default_herb_sutter&#x2F;cvd6hpt?context=1" rel="nofollow">https:&#x2F;&#x2F;www.reddit.com&#x2F;r&#x2F;cpp&#x2F;comments&#x2F;3m0d41&#x2F;writing_good_c1...</a><p>Furthermore, the tool in question does nothing to improve C++&#x27;s capability for safe multithreaded programming, which IMO is Rust&#x27;s actual (yet so often overlooked) ace in the hole.
