Ask HN: thoughts on Wave development language choice?

I just got my Wave sandbox account and am excited to get rolling. Since its APIs are in Java or Python, I'm going to have some learning to do.

Python seems obvious, since I'm a Ruby developer for the most part. But I was wondering about Clojure, if that would work well with the Java API, since it seems like a cool language and I've been competent in Scheme and Java in the past. Has anyone experimented with this?
