This is a project to write a new Haskell standard library from scratch with no concern for backward compatibility. We are currently in the early stages, establishing the goals for the project. The repository is merely a sandbox for ideas, at the moment.
We are currently hosting a darcs project on Patch-tag. There is another repository in case Patch Tag goes down or anything, but it's not necessarily as up to date as the one on Patch Tag. We also have a mailing list. You can also join the #alt-stdlib channel on Freenode for live discussion. Feel free to get involved, especially during these very early stages when your voice can make the most difference.
