title: ramda findIndex with gaps
body: <p>I have the following code where I want to fill in the <code>id</code>, so I'm thinking to write something like this:</p>
  
  <pre><code>const data = [
   { id: 'some-id' },
   { id: 'some-other-id' },
   { id: 'third-id' },
  ];
  
  const tabIndex = R.findIndex(R.propEq('id', R.__))(data);
  </code></pre>
  
  <p>So I can use it like this <code>tabIndex('third-id')</code>, but this is not a function. 
  What do I miss or confuse with this?</p>
  
  <p>The following works </p>
  
  <pre><code>const tabIndex = (id) =&gt; R.findIndex(R.propEq('id', id))(data);
  </code></pre>
  
  <p>But I thought, that is the point of <code>R.__</code> gaps function.</p>
