Seems fair, but refactoring is generally tricky and:

1) replacing a func with a simpler recursive func may or may not be ideal.

2) this fills me with no joy when I read it:

Its enormously hmm… what word to use. Ambitous? Foolish? Brave?

Anyway, taking code, writing some tests for it and then rewriting the entire thing so it passes the tests you wrote only barely falls into “refactoring”.

If anyone refactored my code base by simply rewriting from scratch the parts they dont like, I would be upset.

Rewriting things is hard, and its … brave… to think you can just write a few tests and then if they all pass its all good!

That only works in very trivial examples, and really, doesnt show case the strengths of clojure at all.
