The art of the metaobject protocol

Abstract

From the Publisher: This book presents a new approach to programming language design, which resolves fundamental tensions between elegance and efficiency. Metaobject protocols are interfaces to the lanaguage that gives users the ability to incrementally modify the language's behavior and implementation, as well as the ability to write programs within the language. In this way, a metaobject protocol allows users to adjust the lanaguage to better suit their needs.
