title: Using Yaml attributes within Haml files for Middleman
body: <p>I've created a middleman app and am attempting to use Yaml attributes within my Haml files and am having no success. Here's my very simple code:</p>
  
  <pre><code>\---
  title: This is my title
  \---
  
  / This is my paragraph
  %p Hello world! This is = current_article.title
  </code></pre>
  
  <p>However, the above only generates this:</p>
  
  <pre><code>--- title: This is my title ---
  Hello world! This is = current_article.title
  </code></pre>
  
  <p>I tried the answer from <a href="https://stackoverflow.com/questions/10457920/yaml-front-matter-in-a-haml-file">this</a> question but it doesn't work. Can anyone tell me what I've overlooked or am missing.</p>
