Hi. I spent quite some time figuring out how routes and middlewares can be composed and created a little demo project to show several aspects at https://github.com/ska2342/ring-routes-demo It would be great if someone could review that to see if I worked against common patterns, or the ring contract, or if there are other errors. I would like this to be a good demo for users of ring and compojure who want to go beyond the first tutorials.
