>Rich said one of the reasons he built it was he was programming like this already (pure functions acting on data) but the languages he was using didn’t support it well.

But he could have been using F#, OCaml, Haskell. So it might not be just about pure functions and immutable data.

For being an Haskell and Clojure dev. Data manipulation in Clojure requires a mind shift coming from Haskell. But it feels a lot more straightforward in Clojure. Even if `lens` is incredible. This is like Haskell lenses was were included in the core language if you want. Of course, not type-safe. This is just that, solving problems in Haskell or in Clojure does not really require the same approach. But both ways are delightful. And personally, Clojure has always felt more natural, even though, I also love the Haskell approach.

Rich has talked about all of this, it’s all on YouTube if you’re curious.

The video I remember when he was describing the origin was on 480i, I’ll try to find it
