[Haskell-cafe] accessible layout proposal?

I am in love with this proposal: http://www.haskell.org/haskellwiki/Accessible_layout_proposal However, after some Google searching and contacting its original author, I have still not found any implementation or project to implement it. Are there any I'm missing? And, if not, who would be willing to help undertake a project to patch ghc to support it? Alternatively, you can try to talk me out of liking the proposal so much, but that is much less likely to work. Jimmy Hartzell
