title: Pycharm plugin for attrs?
body: <p><a href="https://github.com/python-attrs/attrs" rel="noreferrer">attrs</a> is a useful package for reducing boilerplate. Example:</p>
  
  <pre><code>class SomeClass(object):
      a_number = attr.ib(default=42)
      list2_of_numbers = attr.ib(default=attr.Factory(list))
  </code></pre>
  
  <p>PyCharm does not offer code completion for the generated <code>__init__</code> method, is there a plugin that can do this? Or some other work around?</p>
