Categorize cljs.core forms

[shaunlebron]

Core is such a mish-mash that it needs categories to make it traversable.

Good start: http://clojuredocs.org/quickref and http://cljs.info/cheatsheet/

It would also be nice to add a meta that differentiate the evaluation, whether it's strict or lazy. Could be simply called :evaluation with values #{:strict :lazy}.

like the difference between map/filter and mapv/filterv? I think most things generate lazy sequences, can you list the ones that you know are "strict"?

[DjebbZ]

Sincerely no idea, I actually counted on your knowledge to enlighten me ;) To be honest, all data literals (and equivalent API) are strict. We stumbled upon this fact when comparing the following : ``` clojure (->> (range 10) (map #(do (println "map") (inc %))) (filter #(do (println "filter") (odd? %))) (take 3) println) ;; All lazy, will print 3 "map filter" then the result (->> [1 2 3 4 5] (map #(do (println "map") (inc %))) (filter #(do (println "filter") (odd? %))) (take 3) println) ;; Strict, will first print 3 "map" then 3 "filter" then the result ``` So in a sense some API of Clojure(Script) are strict. It's not a completely lazy language like Haskell. Only the sequence API is lazy I suppose, but I don't know in details. Maybe worth investigating and documenting ?

Yeah, in that case, I think it's good to categorize just the "strict" ones. Like doall, filterv, mapv, and maybe even doseq and run!, and others we can try to find.

I think this official page can start as a good guide to find more : https://clojure.org/reference/lazy Not sure that "only strict" will suffice. For my part I need to read and test more to truly understand where the distinction lies.
