HOPE 2017
Sun 3 Sep 2017 Oxford, United Kingdom
co-located with ICFP 2017

The HOPE workshop series are intended to bring together researchers interested in the design, semantics, implementation, and verification of higher-order effectful programs. They are informal, consisting of invited talks, contributed talks on work in progress, and open-ended discussion sessions. They are dedicated to John Reynolds, whose work is an inspiration to us all.

The 6th ACM SIGPLAN Workshop on Higher-Order Programming with Effects will take place on Sunday, September 3, 2017, that is, the day before ICFP 2017, in Oxford, United Kingdom.

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, 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.

Call for Talk Proposals

We solicit proposals for contributed talks. We recommend preparing proposals of at most 2 pages, 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, François Pottier (francois.pottier@inria.fr) and Aleks Nanevski (aleks.nanevski@imdea.org).

Important Dates

  • Deadline for talk proposals: June 1st, 2017 (Thursday)
  • Notification of acceptance: July 1st, 2017 (Saturday)
  • Workshop: September 3, 2017 (Sunday)
