title: Pug - generating Select and Options
body: <p>I am new to Pug and I am trying to generate a Select set of Options like this:</p>
  
  <pre><code>select
  each variable in variables
  option(value=variable.id) #{variable.var_name}
  </code></pre>
  
  <p>However the result I get, in the rendered page, is an empty select input followed by the list of options as text</p>
