I agree that this is a pretty good style guide, in the sense that it captures a large portion of what Clojure programmers consider to be good style.

A few words about semicolons for comments. Lots of Clojure code uses ; and ;; and ;;; to indicate levels of comment nesting. I get that multiple semicolons are intended to indicate hierarchy / sections / nesting. Some editors use it for auto-indentation. (However, I don't think editors really need multiple semicolons to do a good job of indentation; mine does fine without.)

Personally, I find one semicolon to be enough to indicate a comment at any level. Context tells the rest. So I am not on-board with multiple semicolons. One, it looks ugly to me. Two, using more than one seems unnecessary -- and unnecessary things are good to avoid unless they add value.

Who else agrees? Is there something I'm missing?
