There's a huge difference in friction between using a language that _also_ has a library for persistent data-structures, vs a language that was designed _around_ immutable datastructures. If you had brought up error messages in Clojure as your main concern, I'd think you'd have a point, but the "putting the paren before the function name confuses me" argument is as old as lisp and pretty moot imnsho. I did Clojure full-time for years, and now do Rust rust full-time, and I can definitely say that Rusts syntax is wayyy more complex and hard to read, despite technically being in the C style syntax family. Great minds discuss architecture, Average minds discuss semantics, Small minds discuss syntax It's also not like the example you posted is easier to read in e.g. javascript if you remove all indentation. (defn f [{x :x y :y z :z [a b c] :coll}] (print x " " y " " z " " a " " b " " c)) const f = ({x: x, y: y, z: z, coll: [a, b, c]}) => print(x, " ", y, " ", z, " ", a, " ", b, " ", c)
