This book constitutes the refereed proceedings of the 23rd European Conference on Object-Oriented Programming, ECOOP 2009, held in Genoa, Italy, in July 2009.

The 25 revised full papers, presented together with the abstracts of 2 invited talks and the ECOOP 2008 banquet speech were carefully reviewed and selected from a total of 117 submissions. The papers cover topics such as types, frameworks and modeling; aliasing and transactions; access control and verification; modularity; mining and extracting; refactoring; concurrency, exceptions and initialization; and concurrency and distribution.

Klappentext

Welcome to the proceedings of ECOOP 2009! Thanks to the local organizersfor working hard on arranging the conference - with the hard work they put in, it was a great success. Thanks to Sophia Drossopoulou for her dedicated work as PC Chair in assembling a ?ne scienti?c program including forward-looking keynotes, and for her e?orts to reduce the environmental impact of the PC meeting by replacing a physical meeting with a virtual meeting. I would also like to thank James Noble for taking the time and e?ort to write up last year's banquet speech so that it could be included in this year's proceedings. One of the strong features of ECOOPis the two days of workshopspreceding themainconferencethatallowsintenseinteractionbetweenparticipants.Thanks to all workshop organizers. Lastyear'ssuccessfulsummerschooltutorialswerefollowedupthisyearwith seven interesting tutorials. Thanks to the organizers and speakers. This year's Dahl-Nygaard award honored yet another pioneer in the ?eld, namely, David Ungar for his contributions includingSelf. I appreciate his e?orts in providing us with an excellent award talk. The world is changing and so is ECOOP. Please contemplate my short note on the following pages entitled On Future Trends for ECOOP.
