title: Reference a method from another class in Ruby
body: <p>I'm doing this:</p>
  
  <pre><code>distanceFunc = lambda do |a,b|
    Leven.wordLevenWithOps(a, b)
  end
  links = prims(phrases, &amp;distanceFunc)
  </code></pre>
  
  <p>It works but I would like to something shorter like:</p>
  
  <pre><code>links = prims(phrases, &amp;Leven.wordLevenWithOps)
  </code></pre>
  
  <p>What is the right syntax ?</p>
