This book constitutes the thoroughly refereed revised selected papers of the 15th International Symposium on Trends in Functional Programming, TFP 2014, held in Soesterberg, The Netherlands, in May 2014. The 8 revised full papers included in this volume were carefully and selected from 22 submissions. TFP is an international forum for researchers with interests in all aspects of functional programming, taking a broad view of current and future trends in the area.

This book constitutes the thoroughly refereed post-conference proceedings of the 23rd International Symposium on Implementation and Application of Functional Languages, IFL 2011, held in Lawrence, Kansas, USA, in October 2011. The 11 revised full papers presented were carefully reviewed and selected from 33 submissions. The papers by researchers and practitioners who are actively engaged in the implementation and the use of functional and function based programming languages describe practical and theoretical work as well as applications and tools. They discuss new ideas and concepts, as well as work in progress and results.

This book constitutes the thoroughly refereed post-conference
proceedings of the 22nd International Symposium on Implementation and
Applications of Functional Languages, IFL 2010, held in Alphen aan den
Rijn, The Netherlands, in September 2010.

The 13 revised full papers presented were carefully reviewed and were
selected from 31 submissions. The IFL symposia bring together
researchers and practitioners that are actively engaged in the
implementation and the use of functional and function based programming
languages. Every year IFL provides a venue for the presentation and
discussion of new ideas and concepts, of work in progress, and of
publication-ripe results.

This book constitutes the thoroughly refereed revised selected papers of the 16th International Symposium on Trends in Functional Programming, TFP 2015, held in Sophia Antipolis, France, in June 2015. The 8 revised full papers included in this volume were carefully and selected from 26 submissions. TFP is an international forum for researchers with interests in all aspects of functional programming, taking a broad view of current and future trends in the area. It aspires to be a lively environment for presenting the latest research results, and other contributions, described in draft papers submitted prior to the symposium.
