The International Workshops on Implementation of Functional Languages (IFL) are a tradition that has lasted for over a decade. The aim of these workshops is to bring together researchers to discuss new results and new directions of research related primarily but not exclusively to the implementation of fu- tional or function-based languages. A not necessarily exhaustive list of topics includes: language concepts, type checking, compilation techniques, (abstract) interpretation, automatic program generation, (abstract) machine architectures, arrayprocessing,concurrent/parallelprogrammingandprogramexecution,heap management, runtime pro?ling and performance measurements, debugging and tracing, tools and programming techniques. IFL 2000 was held at Schloss Rahe, an 18th century castle in Aachen, G- many, during the ?rst week of September 2000. It attracted 49 researchers from the international functional language community, presenting 33 contributions during the four days of the workshop. The contributions covered all topics m- tioned above.In addition, a special session organised by Thomas Arts from the Ericsson Computer Science Laboratory in Stockholm, Sweden, attracted several prac- tioners from industry who reported on their experiences using the functional language Erlang. The Erlang session was sponsored by Ericsson Computer S- ence Laboratory. This year, the workshop was sponsored by local industry (Ericsson Eurolab DeutschlandGmbHanddebisSystemhausAachen),whichindicatesthegrowing importanceoffunctionallanguageconceptsincommercialspheres.Wethankour sponsors for their generous contributions.

This book constitutes the thoroughly refereed post-workshop proceedings of the 11th International Workshop on the Implementation of Functional Languages, IFL'99, held in Lochem, The Netherlands, in September 1999.The 11 revised full papers presented were carefully selected during two rounds of reviewing. The papers are organized in sections on applications, compilation techniques, language concepts, and parallelism.

This volume contains the revised lecture notes corresponding to the lectures given at the 6th International School on Advanced Functional Programming, AFP 2008, held in Heijen, a little village in the woodlands near the city of Nijmegen, The Netherlands, May 19-24, 2008. AFP 2008 was co-located with TFP 2008, the 9th Symposium on Trends in Functional Programming [see P. Achten,P.Koopman,M.Marazan ' : Trends in Functional Programming volume 9, ISBN 978-1-84150-277-9,Intellect]. The school attracted 62 participants from 19 countries, a record, including the lecturers and organizers. This event was precededby?veearlierinstancesinB? astad,Sweden(1995,LNCS925),Olympia, WA, USA (1996, LNCS 1129), Braga,Portugal(1998, LNCS 1608), Oxford, UK (2002, LNCS 2638) and Tartu, Estonia, (2004, LNCS 3622). The goals of the series of Advanced Functional Programming schools are: - Bringing computer scientists, in particular young researchers and progr- mers, up to date with the latest functional programming techniques. - Showinghowtouseadvancedfunctionalprogrammingtechniquesin"progr- ming in the real world".- Bridgingtheeducationalgapbetweenresultspresentedatconferencesonthe one side and material as presented in introductory textbooks on the other side.

This Festschrift has been published in honor of Rinus Plasmeijer, to celebrate the combined occasion of his 61st birthday and the 25th Symposium on Implementation and Application of Functional Languages, IFL 2013, held in Nijmegen, The Netherlands, in August 2013. Rinus Plasmeijer was the main designer of the lazy functional programming language "Clean" and has always been the leader of the associated research team. He has played a decisive role in making the Radboud University of Nijmegen an important center of research in functional programming by organizing and hosting the first few IFL symposia in Nijmegen. This Festschrift contains 19 scientific essays written by former PhD students of Rinus Plasmeijer and researchers in the field of functional programming who have collaborated with him. The authors write about the influence the beauty of functional programming has had or still has on their work.
