I did the first part in F#, and rather than translating Java to F#, I looked at what the author was trying to accomplish in each step, and did something functionally equivalent in idiomatic F#. That was fun & challenging.

haven't tackled the second part, I'm currently down the rabbit hole with Samuel Mimram's Program = Proof, which I'm just loving and the first book I've seen that focuses on the Curry Howard Isomorphism, covering essential logic, lambda calculus, type theory, and Agda... so good.
