Hi Hugo, Msgpack seems like an interesting project indeed. Thanks for making an egg for it!
I'm quite a newbie myself, but I noticed the coops egg includes the module implementation directly<http://bugs.call-cc.org/browser/release/4/coops/trunk/coops-module.scm>, so you don't have to declare two modules. Maybe that's easier in your case too? I also noticed you're using (let () ...). Is there a reason you're not simply using (begin ...)? I've been poking around the msgpack-repositories, they support a lot of languages! It's real neat that Chicken Scheme now joins in on the fun too. So, looking at the node.js port<https://github.com/msgpack/msgpack-node/tree/master/deps/msgpack>, it seems like they've created js-bindings to the official C library. Perhaps this might be suitable for Chicken Scheme too? From what I can tell, you are reimplementing most of the functionality from scratch, is that correct? Great work, great piece of software to keep handy! K.
