title: django: get all columns as a list
body: <p>This is probably very simple, but I just can't figure out how to do it.</p>
  
  <p>I want to get all the columns in some rows as a list. I know I could
  use values_list and flat=True and list all the columns, but is that
  the only way?</p>
  
  <p>I want to do something like this:</p>
  
  <pre><code>rows = FOO.objects.filter(bar='baz')
  </code></pre>
  
  <p>and get a list of lists instead a list of FOO objects.</p>
