title: How do I skip some optional arguments in Robot Framework?
body: <p>My intend is to skip the <strong>${num2}</strong> and <strong>${num4}</strong> arguments.
  But I got an error saying:</p>
  <blockquote>
  <p>Positional argument cannot be used after named arguments</p>
  </blockquote>
  <p>I don't know why it considers the list as a positional argument, shouldn't it be a variable one?</p>
