Dear colleagues,

upon request from several potential contributors, we have postponed the submission deadline for the 6th European Lisp Workshop by two weeks. The new deadline is now April 22nd.

+------------------------------------------------------------+ | CALL FOR PAPERS | | 6th European Lisp Workshop | | July 6, Genova, Italy - co-located with ECOOP 2009 | +------------------------------------------------------------+

Important Dates =============== Submission deadline: April 22, 2009 (EXTENDED) Notification of acceptance: May 08, 2009 ECOOP early registration deadline: May 20, 2009 6th European Lisp Workshop: July 06, 2009

Please note that registration must be done with ECOOP itself. For more information visit http://elw.bknr.net/2009 Contact: Didier Verna, didier@lrde.epita.fr

2009 Special News ================= This year, and for the first time, the workshop proceedings will be published in the ACM Digital Library. Also, the workshop will feature interactive tutorial/demo/coding sessions (see below).

Overview ======== "...Please don't assume Lisp is only useful for Animation and Graphics, AI, Bio-informatics, B2B and E-Commerce, Data Mining, EDA/Semiconductor applications, Expert Systems, Finance, Intelligent Agents, Knowledge Management, Mechanical CAD, Modeling and Simulation, Natural Language, Optimization, Research, Risk Analysis, Scheduling, Telecom, and Web Authoring just because these are the only things they happened to list." -- Kent Pitman

Lisp, one of the eldest computer languages still in use today, is gaining momentum again. The structure of Lisp makes it easy to extend the language or even to implement entirely new dialects without starting from scratch, making it the ideal candidate for writing Domain Specific Languages. Common Lisp, with the Common Lisp Object System (CLOS), was the first object-oriented programming language to receive an ANSI standard and retains the most complete and advanced object system of any programming language, while influencing many other object-oriented programming languages that followed.

This workshop will address the near-future role of Lisp-based languages in research, industry and education. We solicit contributions that discuss the opportunities Lisp provides to capture and enhance the possibilities in software engineering. We want to promote lively discussion between researchers proposing new approaches and practitioners reporting on their experience with the strengths and limitations of current Lisp technologies.

The workshop will have two components: there will be formal talks, and interactive turorial/demo/coding sessions.

Papers ====== Formal presentations in the workshop should take between 20 minutes and half an hour; additional time will be given for questions and answers. Suggested topics include (but are not limited to):

- Experience reports / Case studies - Educational approaches - Software Evolution - Development Aids - Persistent Systems - Dynamic Optimization - Implementation techniques - Hardware Support - Efficiency / Distribution / Parallel programming - Macro-, reflective-, meta- and/or rule-based development approaches - Protocol Meta-programming and Libraries - Context-Oriented, Domain-Oriented and Generative Programming

Interactive Tutorial/Demo/Coding Sessions ========================================= Additionally, we invite less formal talks in the form of interactive tutorial/demo/coding sessions. The purpose of these sessions is to both demonstrate and receive feedback on any interesting Lisp system, either stable or under development. Being less formal than technical paper presentations, it is expected that these sessions be highly interactive.

Submission Guidelines ===================== Potential contributors are encouraged to submit:

- a long paper (around 10 pages) presenting scientific and/or empirical results about Lisp-based uses or new approaches for software engineering purposes,

- a short essay (5 pages) defending a position about where research, practice or education based on Lisp should be heading in the near future,

- a proposal for an interactive tutorial/demo/coding session (1-2 pages) describing the involved library or application, and the subject of the session.

Papers (both long and short) should be formatted following the ACM SIGS guidelines (see http://www.acm.org/sigs/publications/proceedings-templates) and include ACM classification categories and terms (see http://www.acm.org/about/class/1998). Authors will later be required to sign an ACM copyright form.

Submissions should be mailed as PDF to Didier Verna (didier@lrde.epita.fr) before the submission deadline.
