title: Setting id dynamically in jade / id interpolation
body: <p>I've tried all the permutations I can think of but alas with no success.
  I am trying to set an id dynamically in a jade template.</p>
  
  <pre><code>#{page.name}(data-role= 'page', data-theme= 'c', data-url='#{"#"+page.name}')
  </code></pre>
  
  <p>I wondering if it's actually possible.
  Anyone know how to do this?</p>
  
  <p>If some one knows, please help me out - before all my hair falls out :(</p>
