Jade comes somewhat close but opts for the offside rule rather than brackets and abbreviates class and id with . and # respectively.

Just FYI, Jade has been renamed as Pug, for whatever reason. https://github.com/pugjs

Legal reasons :)

Exactly, I'm looking for one that uses brackets instead indentation and the rest is left untouched (no abbreviations or at least not mandatory). I can't find anything already done but at the same time is hard to believe is not done already.
