Came here to say this.  I bumped my head hard on this part of the text - the whole point of using a cliche is that it&#x27;s immediately understandable.  When I come across an incrementing loop that doesn&#x27;t use a cliche variable like &quot;count&quot; or a function that doesn&#x27;t return &quot;return&quot; it increases my mental tax.  The nice thing about using a variable like &quot;count&quot; or &quot;return&quot; throughout your function is it&#x27;s immediately intuitive what&#x27;s going to happen with this variable.
