@Kronuz - that's awesome that you're the maintainer of pyScss - I hadn't realised (obviously!). So you're all over adding in full support for SCSS as and when it gets added upstream?
@jps - Thanks. Not sure why it was including whitespace. My guess is that it's a hangover from the Sass whitespace sensitive syntax. I've changed it now to be essentially the same as the CSS comments. If you're happy with it, you can include the package in the default distro.
