The EuLisp group first met in September 1985 at IRCAM in Paris to discuss the idea of a new dialect of Lisp, which should be less constrained by the past than Common Lisp and less minimalist than Scheme. Subsequent meetings formulated the view of EuLisp that was presented at the 1986 ACM Conference on Lisp and Functional Programming held at MIT, Cambridge, Massachusetts [?] and at the European Conference on Artificial Intelligence (ECAI-86) held in Brighton, Sussex [?]. Since then, progress has not been steady, but happening as various people had sufficient time and energy to develop part of the language. Consequently, although the vision of the language has in the most part been shared over this period, only certain parts were turned into physical descriptions and implementations. For a nine month period starting in January 1989, through the support of INRIA, it became possible to start writing the EuLisp definition. Since then, affairs have returned to their previous state, but with the evolution of the implementations of EuLisp and the background of the foundations laid by the INRIA-supported work, there is convergence to a consistent and practical definition.

The acknowledgments for this definition fall into three categories: intellectual, personal, and financial.

The ancestors of EuLisp (in alphabetical order) are Common Lisp[?], InterLisp[?], LeLisp [?], Lisp/VM [?], Scheme [?], and T [?] [?]. Thus, the authors of this report are pleased to acknowledge both the authors of the manuals and definitions of the above languages and the many who have dissected and extended those languages in individual papers. The various papers on Standard ML [?] and the draft report on Haskell [?] have also provided much useful input.

The writing of this report has, at various stages, been supported by Bull S.A., Gesellschaft f"ur Mathematik und Datenverarbeitung (GMD, Sankt Augustin), Ecole Polytechnique (LIX), ILOG S.A., Institut National de Recherche en Informatique et en Automatique (INRIA), University of Bath, and Universite Paris VI (LITP). The authors gratefully acknowledge this support. Many people from European Community countries have attended and contributed to EuLisp meetings since they started, and the authors would like to thank all those who have helped in the development of the language.

In the beginning, the work of the EuLisp group was supported by the institutions or companies where the participants worked, but in 1987 DG XIII (Information technology directorate) of the Commission of the European Communities agreed to support the continuation of the working group by funding meetings and providing places to meet. It can honestly be said that without this support EuLisp would not have reached its present state. In addition, the EuLisp group is grateful for the support of: British Council in France (Alliance programme), British Council in Spain (Acciones Integradas programme), British Council in Germany (Academic Research Collaboration programme), British Standards Institute, Deutscher Akademischer Austauschdienst (DAAD), Departament de Llenguatges i Sistemes Informatics (LSI, Universitat Politecnica de Catalunya), Fraunhofer Gesellschaft Institut f"ur Software und Systemtechnik, Gesellschaft f"ur Mathematik und Datenverarbeitung (GMD), ILOG S.A., Insiders GmbH, Institut National de Recherche en Informatique et en Automatique (INRIA), Institut de Recherche et de Coordination Acoustique Musique (IRCAM), Ministerio de Educacion y Ciencia (MEC), Rank Xerox France, Science and Engineering Research Council (UK), Siemens AG, University of Bath, University of Technology, Delft, University of Edinburgh, Universit"at Erlangen and Universite Paris VI (LITP).

The following people (in alphabetical order) have contributed in various ways to the evolution of the language: Giuseppe Attardi, JaviereBjar, Russell Bradford, Harry Bretthauer, Peter Broadbery, Christopher Burdorf,eJr^ome Chailloux, Thomas Christaller, Jeff Dalton, Klaus D"assler, Harley Davis, David DeRoure, John Fitch, Richard Gabriel, Brigitte Glas, Nicolas Graube, Dieter Kolb, J"urgen Kopp, Antonio Moreno, Eugen Neidl, Pierre Parquier, Keith Playford, Willem van der Poel, Christian Queinnec, Enric Sesa, Herbert Stoyan, and Richard Tobin.

The editors of the EuLisp definition wish particularly to acknowledge the work of Harley Davis on the first versions of the description of the object system. The second version was largely the work of Harry Bretthauer, with the assistance of J"urgen Kopp, Harley Davis and Keith Playford.
