Are there any good IDEs for Clojure? If so, most of the stumbling could have been avoided. Coding without one tends to fall into the "ball-of-mud" problem where wrong code is built on top of other wrong code. Or alternatively, is there any way to continuously compile Clojure?
Emacs is good for this. A buffer of clojure code in cider-mode can be (re-)compiled easily when you're jacked into a running session (as he does above).
Of course, some of the issues the author faced can't be solved by Clojure's compilation step. When his code fails at runtime in the repl, it compiles successfully.
Emacs has plenty of power here. My preferred Clojure workflow actually involves evaluating Clojure code in a buffer rather than directly at the REPL (so you don't have to do any copy/pasting to edit the code and eval it again). It's easy to build up complex functions piecewise this way.
From my personal experience I love Counterclockwise. Easy shortcuts in Mac make intelligence pissibke. Quick repl with testing. It's pretty great once you get use to load into repl, replay test commands.
