[Haskell-cafe] Style Guide for Haskell Code

After a quick search with Google, it seems that there is not yet an "official" document for Style Guide for Haskell Code. I was only able to found: http://www.cs.caltech.edu/courses/cs11/material/haskell/misc/haskell_style_g... http://urchin.earth.li/~ian/style/haskell.html http://github.com/tibbe/haskell-style-guide/tree/master and, of course, the GHC style guide. Any plans for a common document? Thanks Manlio Perillo
