title: Get Reddit user comments using PRAW causing TypeError: 'SubListing' object is not callable error
body: <p>I'm trying to retrieve the last 1000 comments from a user since 1000 is the Reddit limit. </p>
  
  <p>I followed the code example <a href="https://www.reddit.com/r/redditdev/comments/1n7164/can_i_get_all_comments_of_a_user_by_calling/ccfyhp8/" rel="nofollow noreferrer">here</a>, and modified a few of the calls for the updated API. Such as user.get_comments now seems to be just user.comments. </p>
  
  <p>Here is the code I've run. </p>
  
  <pre><code>import praw
  
  my_user_agent = 'USERAGENT'
  my_client_id = 'CLIENTID'
  my_client_secret = 'SECRET'
  
  r = praw.Reddit(user_agent=my_user_agent,
                       client_id=my_client_id,
                       client_secret=my_client_secret)
  
  user = r.redditor('REDDITUSERNAME')
  
  for comment in user.comments(limit=None):
      print comment.body 
  </code></pre>
  
  <p>I get an error every time on the last line, though. </p>
  
  <pre class="lang-none prettyprint-override"><code>Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
  TypeError: 'SubListing' object is not callable
  </code></pre>
  
  <p>I have connected to the API and have an active connection as I can do print(user.comment_karma) and it displays correctly. </p>
  
  <p>Any ideas what I'm doing wrong?</p>
