I love this book! I do wish there was a new edition that updated the version of Java used in the tree-walk interpreter. There's been some additions to the language, like sealed classes and exhaustive switches, that could really benefit the implementation.

It's a fun little exercise left to the reader to upgrade to current Java. It pretty much eliminates the need for his ad-hoc code generation tool.
Been there, did that, very much enjoy the result.
