IMPORTANT

HIW will now take place alongside Haskell Symposium (Fri/Sat) and no longer be a standalone event. Those interested in HIW and its talks should instead register for Haskell Symposium.

The Haskell Implementors’ Workshop is a forum for those involved in implementing Haskell systems, infrastructure, libraries and tools, for people generally involved in implementing Haskell technology. We share our work and discuss future directions and collaborations with others.

In 2024, the Haskell Implementors’ Workshop will be co-located with ICFP 2024.

The workshop does not have proceedings. Talks and/or demos are proposed by submitting an abstract and selected by a small program committee. The workshop will be informal and interactive, with a flexible timetable and plenty of room for ad-hoc discussion, demos, and impromptu short talks.

Call for Talks

Call for Talks

The 16th Haskell Implementors’ Workshop is to be held alongside ICFP 2024 this year in Milan. It is a forum for people involved in the design and development of Haskell implementations, tools, libraries, and supporting infrastructure to share their work and to discuss future directions and collaborations with others.

Talks and/or demos are proposed by submitting an abstract, and selected by a small program committee. There will be no published proceedings. The workshop will be informal and interactive, with open spaces in the timetable and room for ad-hoc discussion, demos, and lightning talks.

Scope and Target Audience

It is important to distinguish the Haskell Implementors’ Workshop from the Haskell Symposium which is also co-located with ICFP 2024. The Haskell Symposium is for the publication of Haskell-related research. In contrast, the Haskell Implementors’ Workshop will have no proceedings – although we will aim to make talk videos, slides, and presented data available with the consent of the speakers.

The Implementors’ Workshop is an ideal place to describe a Haskell extension, describe works-in-progress, demo a new Haskell-related tool, or even propose future lines of Haskell development. Members of the wider Haskell community are encouraged to attend the workshop – we need your feedback to keep the Haskell ecosystem thriving. Students working with Haskell are especially encouraged to share their work.

The scope covers any of the following topics. There may be some topics that people feel we’ve missed, so by all means submit a proposal even if it doesn’t fit exactly into one of these buckets:

• Compilation techniques
• Language features and extensions
• Type system implementation
• Concurrency and parallelism: language design and implementation
• Performance, optimization and benchmarking
• Virtual machines and run-time systems
• Libraries and tools for development or deployment

Talks

We invite proposals from potential speakers for talks and demonstrations. We are aiming for 20-minute talks with 5 minutes for questions and changeovers. We want to hear from people writing compilers, tools, or libraries, people with cool ideas for directions in which we should take the platform, proposals for new features to be implemented, and half-baked crazy ideas. Please submit a talk title and abstract of no more than 300 words.

Submissions can be made via HotCRP at https://hiw2024.hotcrp.com until July 19 (anywhere on earth).

We will also have a lightning talks session. These have been very well received in recent years, and we aim to increase the time available to them. Lightning talks should be ~7mins and are scheduled on the day of the workshop. Suggested topics for lightning talks are to present a single idea, a work-in-progress project, a problem to intrigue and perplex Haskell implementors, or simply to ask for feedback and collaborators.
