> I'm fluent in prefix notation, but I still have to watch the clojure code that uses #() very carefully.

I think part of this is to encourage you to think about whether another approach would be more appropriate.

Any time I have a #() form with more than three or four tokens in it, it could almost always be better expressed as a private defn or a for expression. And sometimes comp or partial is more appropriate, provided it's still only a handful of functions involved.
