But, looking at the examples (picked the Wordle one since I know that game): https://github.com/HumbleUI/HumbleUI/blob/main/dev/examples/...
I find it extremely hard to read. Even small snippets, say line 56 to 74 which define this "color", "merge-colors" and "colors"... then the "field" one lines 76 to 117 is even harder.
is it more natural read for people familiar with writing functional programs? (am I permanently "broken" due to my familiarity with imperative programing?)
I wonder what the same Wordle example would look like in, say pure Flutter.
Also wonder how would that code look with external dependencies (say hitting a server to get the word of the day), and navigation (with maintaining state in between those pages)
Perhaps you've done it wrong? To read any Lisp code one needs a REPL. And you don't typically type directly in it, you connect to it and eval things from source files. Once you get connected to a REPL, you can eval any expression and sub-expression, and with practice, you'd learn to grok the code without a REPL.
And for writing Lisp, you only need structural editing support in your editor. Once you find basic commands - moving structures around is far more enjoyable process than writing things in an unstructured language.
I am far more productive using Clojure instead of Java and Clojurescript instead of Javascript, Fennel instead of Lua, etc. - it's easier to read, easier to modify, easier to maintain. But, yeah, it does require some practice, just like any other skill.
I'm not sure what you mean by structural editing support. I usually find things like autocomplete or automatic parenthesis to be more of a nuisance than a help.
