Dear Readers,

continuing the tradition started with OOPS (Object-Oriented Programming Languages) at SAC (Symposium on Applied Computing) 2004, this special issue hosts extended versions of papers selected from those submitted to OOPS track at SAC 2007 and to other SAC tracks on topics relevant for object-oriented programming and systems.

The OOPS track promotes extensions and enhancements to the main-stream object-oriented languages and standard systems, and solicits contributions on design, theoretical, and architectural aspects covering a large spectrum of topics, including, programming abstractions, advanced type mechanisms and type safety, multi-paradigm features, language features in support of open systems, aspect-oriented and component-based programming, reection, and program structuring and modularity.

Out of 11 papers submitted to OOPS 2007, 4 full papers and 1 poster were accepted for publication.

We would like to warmly thank all people who made possible the publication of this issue.

The _fth edition of OOPS special track at SAC 2008 will be held in Fortaleza , Brazil , on March 16 - 20, 2008.

Best regards,

Davide Ancona, DISI, University of Genova, Italy
