ACM SIGPLAN

2001 Haskell Workshop

Firenze, Italy, 2nd September 2001

The Haskell Workshop is sponsored by ACM SIGPLAN and forms part of the PLI 2001 colloquium on Principles, Logics, and Implementations of high-level programming languages, which comprises the ICFP/PPDP conferences and associated workshops. Previous Haskell Workshops have been held in La Jolla (1995), Amsterdam (1997), Paris (1999), and Montreal (2000).

Workshop programme

The registration fees and the registration procedure are described here.

The workshop received a total of 23 submissions and after careful consideration the programme committee selected the 10 papers below (6 regular, 4 pearls, and no application letters) for acceptance. The selection was competitive: several good papers had to be rejected.

NEW The proceedings are available as a 4979K PDF file (the programme below contains links to individual papers).

Please, note that in addition to longer presentations on accepted papers, a number of slots for participants to make 10-minute informal presentations are available. To request such a slot, contact Ralf Hinze.

Scope

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. Submissions that discuss limitations of Haskell at present and/or propose new ideas for future versions of Haskell are particularly encouraged. Adopting an idea from ICFP 2000, the workshop also solicits two special classes of submissions, application letters and functional pearls, described below.

Application Letters

An application letter describes experience using Haskell to solve real-world problems. Such a paper might typically be about six pages, and may be judged by interest of the application and novel use of Haskell.

Functional Pearls

A functional pearl presents - using Haskell as a vehicle - an idea that is small, rounded, and glows with its own light. Such a paper might typically be about six pages, and may be judged by elegance of development and clarity of expression.
