Let over Lambda–Lisp 五十年

Let over Lambda–Lisp 五十年
Let over Lambda–50 Years of Lisp (2008)

《Let Over Lambda》是一部2008年出版的高级 Common Lisp 书籍，聚焦于将宏作为编写程序的程序。它旨在教授强大的抽象和生产力技巧，同时启发读者了解 Lisp。2026 年更新说明，该书现在以 HTML 和 PDF 形式免费在线提供，章节将逐步开放，包括关于回指宏和 pandoric-eval 的第 6 章。它还提到了官方日语译本、读者评论、ISBN 978-1-4357-1275-1 以及补充材料。尽管自出版以来编程发生了变化，作者认为它仍然是一个很好的教程，解释了 Lisp 为何特殊。

About the Book

Let Over Lambda (ISBN 978-1-4357-1275-1, 376+iv pp.) is one of the most hardcore computer programming books out there. Starting with the fundamentals, it describes the most advanced features of the most advanced language: COMMON LISP. The point of this book is to expose you to ideas that you might otherwise never be exposed to.

This book is about macros, that is programs that write programs. Macros are what make lisp the greatest programming language in the world. When used properly, macros enable amazing feats of abstraction, programmer productivity, and code efficiency and security that are unheard of elsewhere. Macros let you do things you simply cannot do in other languages.

If you are looking for a dry coding manual that re-hashes common-sense techniques in whatever langue du jour, this book is not for you. This book is about pushing the boundaries of what we know about programming. While this book teaches useful macro skills that can help solve your programming problems today and now, it has also been designed to be entertaining and inspiring. If you have ever wondered what lisp or even programming itself is really about, this is the book you have been looking for.

2026 update: Let Over Lambda was published in 2008, to align with the 50th anniversary of Lisp's invention in 1958. A lot has changed since then, in both Lisp and programming practice in general. Although my thinking and opinions have evolved since, I still believe the book holds up well as a tutorial and explanation of why Lisp so special. Going forward, the entire book is free to read online (HTML, PDF). Happy lisping!
