"A language should have access to its own abstract syntax" - John McCarthy, Father of Lisp. Well, now Groovy 1.6 does! This talk is about why AST transformations are important, what you can do with them, and where the language world is headed. We'll dive into some of the useful Groovy annotations and libraries being written that harness AST transformations, see how to write our own, and work with the brand new AST tools in 1.7. At the end we'll prognosticate about the future of programming languages in general, and hypothesize about where the Groovy features fit into the history of languages. Fun!
