CloudFormation template generation with Clojure

Hey folks, I'm working on a tool to enable the generation of AWS CloudFormation templates using a Clojure-based syntax kind of like leiningen's project.clj. I'm working on how the syntax should look to be most clojurey, and I wonder if anyone has some input: https://gist.github.com/bellkev/7653

A Tuple protocol that defines get0 get1 get3 etc for fast element access that doesn't tie you to using field names might be a good idea. On 8/25/13 9:35 AM, Zach Tellman wrote: > I don't think so, even the existence of all the Tuple* types are an > implementation detail, and you'd need to hint it
