======================================================================== IFL 2026 38th Symposium on Implementation and Application of Functional Languages venue: Aspenäs Herrgård, Gothenburg, Sweden October 28 - 30 2026 https://ifl26.cse.chalmers.se/ ======================================================================== ### Scope The goal of the IFL symposia is to bring together researchers actively engaged in the implementation and application of functional and function-based programming languages. IFL 2026 will be a venue for researchers to present and discuss new ideas and concepts, work in progress, and publication-ripe results related to the implementation and application of functional languages and function-based programming. ### Topics of interest Topics of interest to IFL include, but are not limited to: - language concepts - type systems, type checking, type inferencing - compilation techniques - staged compilation - run-time function specialisation - run-time code generation - partial evaluation - (abstract) interpretation - meta-programming - generic programming - automatic program generation - array processing - concurrent/parallel programming - concurrent/parallel program execution - embedded systems - web applications - (embedded) domain specific languages - security - novel memory management techniques - run-time profiling performance measurements - debugging and tracing - virtual/abstract machine architectures - validation, verification of functional programs - tools and programming techniques ### Peer-review process Following IFL tradition, IFL 2026 will use a post-symposium review process for the formal proceedings. Authors are invited to submit draft papers before the symposium. The program chairs will screen submissions for relevance to IFL, and accepted drafts will be shared with all participants. Each accepted paper must be presented at the symposium by at least one author. If submissions exceed capacity, selection will be based on quality, maturity, and relevance. Authors of accepted presentations will have the opportunity to revise their work in response to symposium feedback and submit a full paper to the post-proceedings. These submissions will be reviewed by the program committee for correctness, novelty, originality, relevance, significance, and clarity. The post-symposium review process is single-blind, with at least three reviews per paper. Camera-ready versions may include minor revisions without further review. ### Important dates Submission of draft papers September 4, 2026 Draft papers notification September 11, 2026 Deadline for early registration September 18, 2026 Deadline for late registration September 25, 2026 IFL symposium October 28-30, 2026 Submission of papers for proceedings November 25, 2026 Notification of acceptance February 12, 2027 Camera-ready version March 12, 2027 Deadlines are end of day Anywhere on Earth (UTC-12). ### Submission details All contributions must be written in English.

================================================================== FINAL CALL FOR NOMINATIONS Richard Bird Distinguished Dissertation Award 2025 Deadline: 31st August 2026 http://tinyurl.com/jfp-bird-award ================================================================= OVERVIEW The Journal of Functional Programming is pleased to establish the Richard Bird Distinguished Dissertation Award, to recognise an outstanding PhD dissertation in functional programming. Richard Bird (1943-2022) was one of the leading figures in functional programming. He was a Professor in Oxford, where he founded the Algebra of Programming group, and served as Director of the Computing Laboratory. Richard is renowned for his many books and pearls on functional programming, which set a lasting standard for clear and elegant writing. It seems fitting that an award be established in his name to further encourage these values in the field. The award includes a prize of £1,000. Funding for the prize is supported by a generous donation from Richard himself to further the cause of functional programming. CRITERIA Eligible dissertations must have been completed in 2025. Depending on the institution, this may be the date of the viva, corrections being approved, graduation ceremony, or otherwise. The award is open to all topics within the remit of JFP, with a particular emphasis on dissertations that reflect Richard's own values of clarity, simplicity and elegance. For a dissertation to be considered for the award it should: - Reach a high standard of exposition; - Make a noteworthy contribution to the subject; - Place the results in the wider context of computer science. NOMINATIONS Please submit the following information to the award chair, <graham.hutton(a)nottingham.ac.uk>, by 31st August 2026: - Two letters of support, explaining why the dissertation should be considered for the award. One letter should be from the advisor/supervisor, and one from an independent source with no conflict of interest with the candidate, such as an external examiner or other expert in the field. - A copy of the dissertation itself. AWARD COMMITTEE Graham Hutton (chair), University of Nottingham Matthew Flatt, University of Utah Jeremy Gibbons, University of Oxford François Pottier, INRIA Wouter Swierstra, University of Utrecht Ningning Xie, University of Toronto The JFP editors-in-chief serve as observers of the committee. ================================================================= This message and any attachment are intended solely for the addressee and may contain confidential information.
