4 Preface Aliasing is one of the key features of object-oriented programming languages, but it is both a blessing and a curse. On one hand it enables the expression of sophisticated designs involving sharing, but on the other hand it makes reasoning about programs difficult for programmers, for tools such as compilers, and for programming verification. This book presents a survey of the state of the art on techniques for dealing with aliasing in object-oriented programming. It marks the 20th anniversary of the paper The Geneva Convention on The Treatment of Object Aliasing by John Hogg, Doug Lea, Alan Wills, Dennis dechampeaux, and Richard Holt, which stressed the need for a systematic study of aliasing in object-oriented programming. Since that paper was published in 1992, several workshops have been devoted to this topic, including the Intercontinental Workshop on Aliasing in Object Oriented Systems (IWAOOS) in 1999 and five instalments of the International Workshop on Aliasing, Confinement and Ownership in object-oriented programming (IWACO) in 2003, 2007, 2008, 2009 and The most recent IWACO was dedicated to 20 years of aliasing in objectoriented languages and at that venue it was decided to produce a state-of-theart LNCS volume dedicated to research in this field. This is the volume you are reading now.papers were solicited from contributors to IWACO and other experts in the area. The result is a broad collection of papers covering many aspects of aliasing in object-oriented programming. Each paper has been extensively reviewed to ensure the highest quality. We hope that this collection will be a valuable addition to researchers bookshelves, and that it will be useful to both active researchers and graduate students alike.
