title: What does it mean that something is transitive in programming?
body: <p>What does it mean that something is transitive with regard to programming? An example is the following (from <a href="http://en.cppreference.com/w/cpp/language/namespace#Using-directives" rel="noreferrer">here</a>):</p>
  
  <blockquote>
    <p>Using-directives are transitive for the purposes of unqualified
    lookup:</p>
  </blockquote>
  
  <p>I am aware of the elaboration of this particular statement, however, I am striving for a more general programming related explanation.</p>
