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.

[Caml-list] [CFP] HOPE'26: ACM SIGPLAN Workshop on Higher-Order Programming with Effects

TL;DR: Talk proposal deadline for HOPE 2026 is on May 29, 2026. This year, the workshop will be co-located with ICFP'26 (Indiana, US) and FW'26 (Paris, France) ---------------------------------------------------------------------- HOPE 2026 The 14th ACM SIGPLAN Workshop on Higher-Order Programming with Effects August 24, 2026 (the day before ICFP 2026) https://icfp26.sigplan.org/home/hope-2026 HOPE 2026 aims to bring together researchers interested in the design, semantics, implementation, and verification of higher-order effectful programs. It will be *informal*, consisting of invited talks, contributed talks on work in progress, and open-ended discussion sessions. ---------------------- Call for Talk Proposals ----------------------- We solicit proposals for contributed talks. We recommend preparing proposals of at most 2 pages excluding references, in either plain text or PDF format. However, we will accept longer proposals or submissions to other conferences, under the understanding that PC members are only expected to read the first two pages of such longer submissions. When submitting talk proposals, authors should specify how long a talk the speaker wishes to give. By default, contributed talks will be 30 minutes long, but proposals for shorter or longer talks will also be considered. Speakers may also submit supplementary material (e.g. a full paper, talk slides) if they desire, which PC members are free (but not expected) to read. We are interested in talks on all topics related to the interaction of higher-order programming and computational effects. Talks about work in progress are particularly encouraged. If you have any questions about the relevance of a particular topic, please contact the PC chairs, Taro Sekiyama (tsekiyama@acm.org) and Francesco Gavazzo (francesco.gavazzo@unipd.it). Important Note: HOPE’26 will be co-located with ICFP’26 (https://icfp26.sigplan.org/) and FW’26 (https://www.irif.fr/~scherer/events/fpw-2026/announce.html). Presenters can choose either event to attend in-person. We also encourage remote participation and will support remote presentations. Deadline for talk proposals: May 29, 2026 (Friday) Notification of acceptance: June 26, 2026 (Friday) Workshop: August 24, 2026, Indiana, United States & Paris, France (tentatively) The submission website is now open: https://hope26.hotcrp.com --------------------- Workshop Organization --------------------- Program Committee: Yuyan Bao (Augusta University) Raphaëlle Crubillé (Aix-Marseille University) Francesco Dagnino (University of Genova) Elena di Lavore (University of Oxford) Francesco Gavazzo (University of Padua) Cristina Matache (University of Edinburgh) Ken Sakayori (The University of Tokyo) Taro Sekiyama (National Institute of Informatics) Dario Stein (Radboud University) Niels Voorneveld (Cybernetica) Zhixuan Yang (University of Exeter) --------------------- Goals of the Workshop --------------------- A recurring theme in many papers at ICFP, and in the research of many ICFP attendees, is the interaction of higher-order programming with various kinds of effects: storage effects, I/O, control effects, concurrency, etc. While effects are of critical importance in many applications, they also make code harder to build, maintain, and reason about. Higher-order languages (both functional and object-oriented) provide a variety of abstraction mechanisms to help “tame” or “encapsulate” effects (e.g. monads and handlers, ADTs, ownership types, typestate, first-class events, transactions, Hoare Type Theory, session types, substructural and region-based type systems), and a number of different semantic models and verification technologies have been developed in order to codify and exploit the benefits of this encapsulation (e.g. bisimulations, step-indexed Kripke logical relations, higher-order separation logic, game semantics, various modal logics). But there remain many open problems, and the field is highly active. The goal of the HOPE workshop is to bring researchers from a variety of different backgrounds and perspectives together to exchange new and exciting ideas concerning the design, semantics, implementation, and verification of higher-order effectful programs. We want HOPE to be as informal and interactive as possible. The program will thus involve a combination of invited talks, contributed talks about work in progress, and open-ended discussion sessions. There will be no published proceedings, but participants will be invited to submit working documents, talk slides, etc., to be made available online. -- Taro Sekiyama
