title: Does Coffeescript support nested list comprehensions?
body: <p>For example, given the following structure</p>
  
  <pre><code>    pages = [
          [
              { myvar: 1},
              { myvar: 2},
              { myvar: 3},
          ]
      ];
  </code></pre>
  
  <p>How can I express the folling (python-like) comprehension?</p>
  
  <pre><code>v.myvar for p in pages for v in p
  </code></pre>
