Proceedings of the 2004 ACM SIGPLAN workshop on Haskell

It is my great pleasure to welcome you to the ACM SIGPLAN 2004 Haskell Workshop. The purpose of the Haskell Workshop is to discuss experience with Haskell, and possible future developments for the language. The scope of the workshop includes all aspects of the design, semantics, theory, application, implementation, and teaching of Haskell.The 2004 Haskell Workshop takes place on 22 September, 2004, in Snowbird, Utah, USA, in affiliation with the 2004 International Conference on Functional Programming (ICFP'04). The call for papers attracted 27 submissions. Each paper was evaluated by at least three international referees. During a five-day electronic meeting, the program committee selected nine of the submissions for presentation at the workshop as full papers based on the referee reports. The program committee also selected a student paper for a short presentation. Additionally, two tool demonstrations, the abstracts of which are included in these proceedings, were selected from five proposals. The 2004 workshop program also includes the annual The Future of Haskell discussion.
