The syntax is quite a bit like Haskell but that's mostly surface level here and imo it's quite it a bit simpler and easier to pick up. I'm curious what you mean by comparing it to Clojure when Unison is not really lispy at all.

Personally I found Unison easy to pick up the basics for despite being unfamiliar with Haskell beforehand (although underlying ideas of how to structure things took a bit of time for me to figure out).
