title: Is there a difference between "raise exception()" and "raise exception" without parenthesis?
body: <p>Defining a parameterless exception:</p>
  
  <pre><code>class MyException(Exception):
      pass
  </code></pre>
  
  <p>When raised, is there any difference between:</p>
  
  <pre><code>raise MyException
  </code></pre>
  
  <p>and</p>
  
  <pre><code>raise MyException()
  </code></pre>
  
  <p>I couldn't find any; is it simply an overloaded syntax?</p>
