title: Scalaz .option - what is this shorthand for?
body: <p>I'm seeing the following code:</p>
  
  <pre><code>val a  = (x: Int) =&gt; (x == 1).option(doSomethingUnrealiable(1))
  </code></pre>
  
  <p>Is this equivalent to:</p>
  
  <pre><code>val a  = (x: Int) =&gt; if (x == 1) Option(doSomethingUnrealiable(1))
  </code></pre>
  
  <p>I ask because I'm struggling to find doco on Scalaz for this <code>.option</code> method. </p>
