&quot;<span style="font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">But my </span><span style="font-family:arial,sans-serif;font-size:13px;background-color:rgb(255,255,255)">point was that a programmer should understand the standard&quot;</span><br>
<br><div>But suppose the standard does not evidently aim to be understood, in the generally understood meaning of &quot;understood&quot;,</div><div>or there are more words in the standard than will ever appear in the programmer&#39;s own programs?</div>
<div>Worse! &quot;Standard&quot; doesn&#39;t imply a fixed point (&quot;oh, that syntax/semantics is so last year!&quot;).</div><div>I think looking into memset and deciding it&#39;s not worthwhile calling is perhaps overly enthusiastic.</div>
<div>Actually, it&#39;s wrong, because it overlooks the side-effect, and an optimiser for a language with side-effects</div><div>should take that into account.</div><div><br></div>
