title: Stack Level Too Deep: retrieving an ID of a List - Gibbon / MailChimp / Rails
body: <p>What is the proper way to retrieve an id of a list from MailChimp using Gibbon API Wrapper? </p>
  
  <p>Say I want to do something like: </p>
  
  <pre><code>list = gibbon.lists.list(filters: "Foo")
  gibbon.lists(list.id).members.create(....)
  </code></pre>
  
  <p><code>list.id</code> returns <code>stack level too deep</code> because of the nested attributes inside the <code>gibbon.list</code>call. What is the correct way to call <code>list.id</code> in Gibbon? </p>
