— Brian Harvey, Lecturer, Computer Science Division, University of California, Berkeley, and author of the series "Computer Science Logo Style"
"This book follows in the fine tradition of Abelson/Sussman and Kamin's book on interpreters, but goes well beyond them, covering functional and Smalltalk-like languages as well as more advanced concepts in concurrent programming, distributed programming, and some of the finer points of C++ and Java."
— Peter Norvig, Director of Search Quality, Google Inc., and co-author of "Artificial Intelligence: A Modern Approach"
"The authors do a remarkable job of illuminating some difficult concepts with plain language. An excellent book for novice or mid-level programmers seeking deeper understanding of the art."
— Eric S. Raymond, Open Source advocate, author, and developer
