C55: More Info?

Question

I saw a PyCon09 keynote presentation (slides: http://www.slideshare.net/kn0thing/ride-the-snake-reddit-keynote-pycon-09?c55) given by the reddit guys, and in it they mention a CSS compiler called C55. They said it would be open sourced soon. It looks cool - does anyone have more information about how it works, why they created it (aside from the fact that CSS is a pain), etc...?

Answer 1

Just from the talk, the main advantage over simply generating CSS from templates is that it allows nesting, which is conceptually a lot nicer to work with.

So you could do something like this in C55 (obviously I'm kind of making up the syntax):

div.content
{
  color: $content_color ;

  .left
  {
    float: left;
  };
  .right
  {
    float: right;
  };
};
