the lil&#x27; printf seems like a lil&#x27; snarky s---.<p>I&#x27;m somewhat reminded of &quot;learn programming&quot; chatrooms, where a majority of discussions take the form of &quot;how would I do X&quot; &quot;don&#x27;t do X&quot;. Then that is the end of it.<p>The person&#x27;s problem stays unsolved, the answerer gets the satisfaction of putting someone down, good times.
