Proceedings of the 2006 ACM SIGPLAN workshop on Haskell

It is with great pleasure that I present to you the proceedings of the 10th ACM SIGPLAN Haskell Workshop -- Haskell'06. The purpose of the workshop is to discuss experience with Haskell and possible future developments of the language. Topics of interest are all aspects of the design, semantics, theory, application, implementation and teaching of Haskell. Since 1997, the Haskell Workshop has been co-located with ICFP -- the International Conference on Functional Programming.This year's call for papers attracted 24 submissions of full papers. Each of the papers was reviewed by at least 3 international reviewers. During a five-day electronic meeting, the Program Committee selected 10 papers for publication in these proceedings and presentation at the workshop. In addition, we accepted 3 demos and a status report on Haskell' -- the next revision of the Haskell language. Also, the program includes the traditional discussion on the "Future of Haskell".
