Most of this, even if it&#x27;s not my preference, I would never bother arguing with.  But I have a question about a practice that is tremendously widespread.<p>I have real trouble with single-letter variable names like &quot;c&quot;, for any function more than, say, 2-3 lines.  I scan the code and it <i>increases</i> my mental load because I have to remind myself what it means.<p>Obviously a lot of people don&#x27;t have problems with this, but I do.  Anybody else?<p>Maybe it&#x27;s because I jump around a lot from function to function?
