title: How to count number of items in queryset without count()
body: <p>I'd like to count the number of items returned in my queryset. For example</p>
  
  <p><code>userdesigns = Design.objects.filter (desadder = user.id)</code></p>
  
  <p>I'd like to get the number of object returned <strong>without</strong> using count().</p>
  
  <p>The reason is that I'm trying to speed up performance and reduce the number of database queries that I perform and I noticed that using count() pings the database, which I don't want. Considering I already pulled the complete lets of userdesigns, shouldn't there be a way to just count the number of items stored in that returned queryset?</p>
