I'm a bigger fan of `.sass` syntax over the `.scss` syntax (because it's better, let the war begin!), so that's what I'm trying to use. When trying to compile a `.sass` file with Elixir, however, it seems to be trying to use `scss` syntax to compile.

```
elixir(function(mix) {
  mix.sass('styles.sass');
});

```

When `styles.sass` is

```
body
  background: black

```

I get the following errors:

```
$ gulp
[17:54:43] Using gulpfile ~/sites/skynet/gulpfile.js
[17:54:43] Starting 'default'...
[17:54:43] Starting 'sass'...
[17:54:43] Finished 'default' after 185 ms
[17:54:43] gulp-notify: [Laravel Elixir] Error: invalid top-level expression
[17:54:43] Finished 'sass' after 198 ms

```

But changing `styles.sass` (still keeping the `.sass` extension), to

```
body {
  background: black;
}

```

I get a successful compilation. Does Elixir only compile `scss` syntax or am I missing some sort of config setup? Help much appreciated!
