title: Ruby block code in haml
body: <p>The code below is working</p>
  
  <pre><code>-@items.each do |item|
   %tr
    %td
     =item.quantity
     times
    %td= item.product.title
   end
  </code></pre>
  
  <p>However I want to use <code>{ }</code> instead of <code>do ... end</code>. Is it possible?</p>
  
  <pre><code>-@items.each { |item|
   %tr
    %td
     =item.quantity
     times
    %td= item.product.title
   }
  </code></pre>
  
  <p>For some reason it throws an exception. What did I do wrong?</p>
