title: Sass looping through class names starting with number
body: <p>I am looping through a list of names in sass and it seems that the sass is breaking when it arrives at a point where the class names starts with a number. Infact when i commented out the class names starting with a numeric value, the sass compilation worked fine. That said i cannot rename the class names. How I can make it work? Below is the code im trying:</p>
  
  <pre><code>@each $car in
    bmwwhite
    hondared
    //22ltr-porche
    //30ltr-cossworth
   {
    .#{$car} {
      background:url(/img/cars/#{$car}.jpg) no-repeat 
    }
   }
  </code></pre>
