This book constitutes the refereed proceedings of the 4th International Symposium on Practical Aspects of Declarative Languages, PADL 2002, held in Portland, OR, USA in January 2002. The 18 revised full papers presented together with three invited contributions were carefully reviewed and selected from 37 submissions. Among the topics addressed are objects, ACL, higher order logic programming, compilers, embedded programs, types, XML parsing, texture generation, logic programming, generic programming, modeling languages, Prolog programming, garbage collection, etc.

Declarative languages build on sound theoretical bases to provide attractive frameworks for application development. These languages have been succe- fully applied to a wide variety of real-world situations including database m- agement, active networks, software engineering, and decision-support systems. New developments in theory and implementation expose fresh opportunities. At the same time, the application of declarative languages to novel problems raises numerous interesting research issues. These well-known questions include scalability, language extensions for application deployment, and programming environments. Thus, applications drive the progress in the theory and imp- mentation of declarative systems, and in turn bene?t from this progress. The International Symposium on Practical Applications of Declarative L- guages (PADL) provides a forum for researchers, practitioners, and implementors of declarative languages to exchange ideas on current and novel application - eas and on the requirements for e?ective use of declarative systems. The fourth PADL symposium was held in Portland, Oregon, on January 19 and 20, 2002.

ETAPS2008wasthe11thinstanceoftheEuropeanJointConferencesonTheory and Practice of Software. ETAPS is an annual federated conference that was established in 1998 by combining a number of existing and new conferences. This yearit comprised?ve conferences (CC, ESOP,FASE, FOSSACS, TACAS), 22satelliteworkshops(ACCAT,AVIS,Bytecode,CMCS,COCV,DCC,FESCA, FIT, FORMED, GaLoP, GT-VMT, LDTA, MBT, MOMPES, PDMC, QAPL, RV,SafeCert,SC,SLA++P,WGT,andWRLA),ninetutorials,andseveninvited lectures (excluding those that were speci?c to the satellite events). The ?ve main conferences received 571 submissions, 147 of which were accepted, giving an overall acceptance rate of less than 26%, with each conference below 27%. Congratulationsthereforetoallthe authorswhomadeittothe ?nalprogramme! I hope that most of the other authors will still have found a way of participating in this exciting event, and that you will all continue submitting to ETAPS and contributing to make of it the best conference in the area. The events that comprise ETAPS address various aspects of the system - velopment process, including speci?cation, design, implementation, analysis and improvement.The languages, methodologies and tools which support these - tivities are all well within its scope. Di?erent blends of theory and practice are represented, with an inclination towards theory with a practical motivation on the one hand and soundly based practice on the other. Many of the issues involved in software design apply to systems in general, including hardware s- tems, and the emphasis on software is not intended to be exclusive.
