agree, I'm using pipelines in Elm, which is almost the same syntax as in OCaml (piping into the last argument). I dislike "<|" b/c of the flexibility syndrome. It's frequently used in Elm in order to avoid parentheses. Same with Elixir, but it's missing currying, so it does piping into the first argument. Clojure has both thread-first and thread-last macros. The problem with these approaches is that they are optional. Ideally the point-free programming will be the default, not an optional style. I agree that pipelines in Elm and Elixir are much more readable than point-free code in Forth and APL ;) Unlike the ML-family languages, in APL/J/K/q you can omit any combination of arguments: f:{x-y} f[1] same as f[1; ] f[;1] same as f[ ;1] f same as f[ ; ]
