[Haskell-cafe] [GSOC] About "Implementing Maps using generalized tries" project idea

Hi, I was looking at the list of Haskell GSOC 2009 project ideas, and I came across the one in which we have to implement maps using generalized tries. However, I also found this as one of the GSOC 2008 projects. I want to know if this project is still open, or the required work has been done last year. If it's open, what exactly needs to be done further. Regards Gautam
