Partway through, I recognized the function calling syntax as similar to Nix which I just started learning. Turns out the implementation of the article is in Haskell, another declarative language. At work. we use Power Query with it's M language - a declarative language with lazy evaluation. Is there something about declarative languages that makes them especially suitable for data work?
