title: Enzyme .eq() or .index()?
body: <p>Enzyme has a cheerio-like set of selector functions, but it doesn't seem to have <code>.eq()</code> or <code>.index()</code>. I couldn't find a super-specific set of functions it does implement anywhere in their documentation.</p>
  
  <p>Is there a function like <code>.eq()</code> or <code>.index()</code> I can use to get a specific element at a specific index. </p>
  
  <p><code>:nth-child()</code> doesn't appear to be implemented and <code>.get()</code> unwraps it, which I don't particularly want.</p>
