Corollary: Write code such that it&#x27;s easy to use <i>grep</i> to find where things are used.<p>One of my pet peeves is when OO programmers take class&#x27;s separate namespaces as a license to use super-generic method names.  Method names like &quot;add&quot;, &quot;update&quot;, etc.  Makes it near impossible to figure out where those methods are used!
