I can't really be the only one here who thinks that this kind of discussion of extensions to the syntax of Haskell is totally inappropriate when we have a large number of already implemented extensions to the language whose interactions with each other are largely undocumented. The Haskell Report isn't the place to be talking about new features, in my mind. If this project turns into bike-shedding the concrete syntax of the language, it's hard to imagine real progress being made on the actual problem, which is that the Haskell Reports as they stand are not as relevant as they should be with regard to the language in which we're writing programs today.
In my opinion, this sort of bikeshed discussion of new features is the main reason that H2010 didn't really get very far relative to H98. If you personally want the ability to insert additional commas at the beginning or end of lists, perhaps a better plan is to start with asking the GHC developers with where to begin on a patch to the parser. Then once everyone is using your extension, some future Haskell Report can perhaps document it. I'm sorry if this comes off as harsh, and I don't really mean to be picking on Alexander specifically here, but I'd really like for the next Haskell Report to be relevant to the language we're using today, and I think there's too much to be done in the direction of reporting on the things we already have to even consider things which are unimplemented, or even things which were only *just* implemented.
