title: Winless NameError despite variables being imported
body: <p>I'm using Notepad++ and in my settings I have <code>UTF-8 without BOM</code> checked. But still when Winless auto-compiles my .less files it returns a <code>NameError: variable @background is undefined ...</code>.</p>
  
  <p>I've read that Notepad++ should be fine when working with .less files and imports, but somehow it's still causing trouble. If Notepad++ is the problem, that is.</p>
  
  <p>Anybody an idea what could be the problem?</p>

  body {
      font: 12px Arial;
      color: #333;
      background: @background;
  }
  
  b { font-weight: bold }
  i { font-style: italic }
  u { text-decoration: underline }
