Strange that the post makes no mention of the Little Schemer series, because teaching you to "think Scheme" is exactly what those books do. Some people are put off by the weird style (combination of children's book visuals and socratic logic problem presentation), but they work!

I love that book so much, it helped me grokk the more lambda calculus aspect of FP more than anything.

A few chapters in I belly laughed when it dawned on me that it's going to be recursion until the cows come home. The authors insistence on working through the steps is endearing and comical. Great book to come back to every once in a while.

I struggled with The Little Lisper (as it was called at the time) in school but as I approach the other end of my career I've given some thought to working through it again. I think it would come a lot more easily now. Though I looked at Haskell maybe 10 years ago and never got traction with it.

Functional or declarative programming styles appeal to me, and I love what I've learned of Erlang but never really had a job where I could use it. Used SQL a lot and quite like it as well.
