Finally got through the mighty Practical Common Lisp tome. The style of the book is written in a nice mix of theory and practice (with relevant and good examples). My friend Lau asked me why on earth I would want to read a book on Lisp? A fair question since Lisp is really old, actually measured in computer time it might even be called ancient. But I had two main motivations for reading the book, to become a better programmer and secondly to better understand new language features introduced in languages like Boo and C#. Just look at the new LINQ features in C# 3.0 and specifically this video.
I wholeheartedly recommend this book to anyone interesting in a good programming book.
