For a while now, I've been working on a book on Domain Specific Languages. This page is a gateway into my Work In Progress on the book. My current vision for the book is a Duplex Book, split into a section of narratives and a (larger) reference section of topics. At the moment most topics are in pattern form, but I don't expect this to be necessarily the case as I flesh them out. Reference items in parenthesis are just placeholders for material that I'll be writing later.
