Step by step debugging

I'm a big fan of edebug, the Emacs debugger, which allows step through debugging (and breakpoints, and some more fun.) Is there anything similar for Clojure? For example, from an Emacs (cider) REPL, I'd evaluate some Clojure expression, then a window would let me go through a buffer containing a
