Exploring if I can get Respo component simpler. Tried in Lumo.

a.cljs

(ns demo.a
  (:require [demo.b :refer [defcomp]]))

(defcomp my-comp [x y] 1)

(println my-comp)

b.clj

(ns demo.b)

(defmacro defcomp [comp-name params body]
  `(def ~comp-name
    (demo.b/create-comp ~(keyword comp-name)
      (~'fn [~@params]
        (~'fn [~'cursor] ~body)))))

b.cljs

(ns demo.b
  (:require-macros [demo.b]))

(defn create-comp [comp-name body]
  [comp-name body])
