(defmacro afor
  "Like for but eagerly builds a JS array.
  Usually for react consumption."
  [[item coll] & body]
  `(reduce (fn [neue# ~item]
              (.push neue# (do ~@body))
              neue#)

(defmacro arfor
  "Like for but eagerly builds a JS array.
  Usually for react consumption."
  [[item coll] & body]
  `(reduce (fn [neue# ~item]
              (.push neue# (html ~@body))
              neue#)
            (cljs.core/array) ~coll))

(defmacro arifor
  "Like arfor also gives the index. Syntax is like this to allow cursive to give variable
  highlighting. Note: not destructing is happening. A fast reduce with an index is done.
  (arifor [[idx item] items]
    [:div {} idx  \":\" item])"
  [[[idx item] coll] & body]
  `(let [coll# ~coll
         neue# (cljs.core/array)]
     (reduce (fn [~idx ~item]
               (.push neue# (html ~@body))
               (inc ~idx))
             0 coll#)

Will need a html macro which can be like:

(defmacro html
  [body]
  (sablono.compiler/compile-html body))
