title: Why does inspect() think map isn't built in?
body: <p>The following code returns false</p>
  <pre><code>import inspect
  print(inspect.isbuiltin(map))
  </code></pre>
  <p>But the map function is listed under <a href="https://docs.python.org/3/library/functions.html" rel="noreferrer">&quot;built-in&quot; functions</a>.</p>
  <p>Why is it so?</p>
