Google Common Lisp style guide
&gt; Symbol guidelines: You should use lower case<p>Like flipping through for the soft porn in a friend&#x27;s &quot;romance&quot; novel, I must confess I searched straight for this guideline.<p>It astonishes me that Lisp systems still default to all caps. Of course one can quickly disable this, but why send the old gheezer &quot;GET OFF MY LAWN!&quot; message? That&#x27;s exactly what people do, get off Lisp&#x27;s lawn. They don&#x27;t even get to the part where the parentheses (completely unnecessary for representing a tree in 2020) are a hazing exercise &#x2F; loyalty test.<p>I love Lisp, but its public relations is the poster child for &quot;How can people who are so smart be so dumb?&quot;
