title: HAML render in Prepros App - bug or just me?
body: <p>I can't get including partial files in HAML to work.</p>
  
  <p>I have a code from basic HAML tests</p>
  
  <pre><code># file: partial_layout.haml
  %h1 Partial layout used with for block:
  = render :layout =&gt; 'layout_for_partial' do
    %p Some content within a layout
  </code></pre>
  
  <p>And second file</p>
  
  <pre><code># file: _layout_for_partial.haml
  .partial-layout
    %h2 This is inside a partial layout
    = yield
  </code></pre>
  
  <p>So i click a compile button in Prepros App...</p>
  
  <pre><code>Exception on line 2: undefined method `render' for #&lt;Object:0x2a196c8&gt;
    Use --trace for backtrace.

  </code></pre>
  
  <p>This should be basic HAML function. What am I doing wrong?</p>
