Here a short summary by Malcolm and me of the final discussion at the Haskell workshop: First Simon Peyton Jones stated that the Haskell'98 Report continues to be revised in small ways for correctness and readability. He will continue this until a whole month passes with no further changes, then issue a finalised new version (so send bug reports now). John Launchbury and many further people made a plea that the single biggest hindrance to the further spread of Haskell is the lack of a standard cross-platform GUI. Alas, no answer to the problem was found. There is no agreement which (existing) library could be the basis of a standard one and nobody wanted to commit himself to developing and supporting such a library. Well, Manuel Chakravarty promised to continue developing the GTK+ binding and would be happy about people helping him. (The GUI library presented at the workshop is not intended to solve the standard GUI problem.) Rather than starting work on a successor to Haskell, people generally want to see `blessed addendums' to the Report, for common agreed extensions, e.g. FFI, exceptions, concurrency, MPTC, fundeps, etc. The FFI addendum is almost ready, but any others need volunteers, not to mention agreement between designers and implementations. The idea is that a solid reference definition/documentation of each extension should exist independent of any particular compiler (but there is a lack of volunteers). It was noted that the future job of designing Haskell-2 will be made much easier by many small steps rather than one large effort. My personal comment about application letters: I think your idea of a poster session with abstracts in the proceedings is very good. In fact, anybody already had the possiblity to give a 10 minute talk. But there was no special invitation to talk about applications and an abstract would certainly be useful for people not attending or future reference. Here a list of the 10 minute talks given at the workshop (Ralf, maybe you can put them on the workshop web page?): Simon Marlow: Haskell Libraries, The Next Generation Presentation of the hierarchical structure. Need more libraries and maintainers for them. Would like to have HaskellDoc and some standard testing method. Mark Shields: Lightweight Modules for Haskell Shortly stated that he is working on a new module system and would like every interested person to join. Wolfram Kahl: Animating Haskell by Term Graph Rewriting HOPS is a system for term graph rewriting that can also show the rewriting steps in a graphical animation. Similar to GHood but all intermediate redexes are shown. Translation of Haskell programs into HOPS by hand. Useful especially for understanding space leaks. Martin Sulzmann: TIE: A CHR-based Type Inference Engine He reformulates context simplification of Haskell classes in the constraint handling rule formalism. This gives a flexible framework for all kinds of extensions and variants of class systems. Manuel Chakravarty: A standard Foreign Function Interface for Haskell98 Basically finished (general part and C, not for Java). Solicits last comments from the general community. -- OLAF CHITIL, Dept. of Computer Science, University of York, York YO10 5DD, UK.
