title: How do I indent list comprehension in CoffeeScript?
body: <p>I have the following line of <code>CoffeeScript</code>:</p>
  
  <pre><code>names = (mail.folder for mail in @data when mail.service_name is service.name).unique()
  </code></pre>
  
  <p>This line is too long, so it won't pass linting by <code>CoffeeLint</code>.</p>
  
  <p>I'm trying to break it, but I always get indentation errors by <code>CoffeeLint</code>.</p>
  
  <p>What is the proper way to indent this?</p>
