For example setting up the interface. Note: Over one in five interfaces in the Emacs source uses Lisp and not the `interactive' format string. So it isn't just me. It takes _a lot_ of time setting up the interface, assigning default values, verifying indata, setting up collections for completion, and so on. Here is one example from my own code: ;; ... (interactive (if (numberp current-prefix-arg) (list current-prefix-arg) current-prefix-arg)) (unless end (setq end 73)) (unless step (setq step (min 10 (max 2 (/ end 10))))) (unless i (setq i 0)) (unless (and (numberp i) (<= 0 i) (numberp end) (< 0 end) (numberp step) (< 0 step)) (error "Bogus indata")) This is 402 chars! But here is a 135-char solution that expresses the same: [ end :range 0< :default 73 :prefix-arg step :range-cut 2-10 :default (/ end 10) i :range 0<= :default 0 ] And here is a 88 char solution: [ end :r 0< :d 73 :pa step :rc 2-10 :d (/ end 10) i :r 0<= :d 0 ] Also with: :prompt-string (:ps), :doc-string (:ds) ... That way, we could keep Lisps elegance and power for where people cared about it, for example solving interesting algorithmic problems. -- underground experts united https://dataswamp.org/~incal
