Description of  Pattern-oriented software architecture, vol.4: patterns for distributed computing

0470059028 pdf Offering an alternative approach to multiparadigm programming concepts, this work presents the four major language paradigms - imperative, object-oriented, functional and logical - through a new, common language called Leda. It: introduces the important emerging topic of multiparadigm programming - a concept that could be characterized as "the best of" programming languages provides a coherent basis for comparing multiple paradigms in a common framework through a single language and gives both a technical overview and summaries on important topics in programming-language development Foreword.
