One-liner: the list of accepted talks for HOPE 2017 is now online! ------------------------------------------------------------------------------ CALL FOR PARTICIPATION HOPE 2017 The 6th ACM SIGPLAN Workshop on Higher-Order Programming with Effects September 3, 2017 Oxford, United Kingdom (the day before ICFP 2017) http://icfp17.sigplan.org/track/hope-2017-papers#event-overview ------------------------------------------------------------------------------ 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. # Important Dates * Workshop: September 3, 2017 (Sunday) # Accepted Talks http://icfp17.sigplan.org/track/hope-2017-papers#event-overview # Workshop Organization Program Co-Chairs: François Pottier (Inria Paris) Aleks Nanevski (IMDEA Software Institute) Program Committee: Edwin Brady University of St Andrews Pierre-Évariste Dagand LIP6/CNRS Atsushi Igarashi Kyoto University Robbert Krebbers Delft University of Technology Vivek Nigam Federal University of Paraíba Matija Pretnar University of Ljubljana Azalea Raad Imperial College London Aseem Rastogi Microsoft Research Filip Sieczkowski University of Wrocław Niki Vazou University of Maryland
