> I find some code easier to express with procedural/mutable loops than recursion

This is what I was talking about in the section "Unlearning and relearning". While there are _some_ domains (like embedded systems) for which Haskell is a poor fit, a lot of the difficulties people have with it (and with FP in general) is that they have been heavily educated to think in a particular way about computation. That's an accident of history, rather than any fundamental issue with the programming paradigm.

How does one go from years and decades of imperative programming to becoming fluent in Haskell's style of functional programming? It feels like a steep price to pay when most over languages don't require such substantial re-learning.

I don't think it's specifically Haskell's style of functional programming. It's just functional programming.

Any paradigm shift requires re-learning I think. I don't actually think that's particularly hard, nor do I think it means the paradigm isn't a good one, it's just an inevitable consequence of a paradigm shift. Some shifts are easier than others, if the paradigms are closer together, but functional and imperative programming are quite distant in my view.

Nevertheless, I've seen some people find this easy, others find it hard. YMMV I guess.
