As an aside, I would have liked (some pred coll) to return the item
that makes the pred true and the current implementation of `some to be
renamed `any? so that we would have the following:

Ya know, I was considering not posting my code. But the thought did

Shouldn't this return nil ? :
1:4 user=> (find-first-result false? [true])
false

(defn find-first-result [pred coll]
(find-first identity (map pred coll)))
=>
1:22 user=> (find-first-result false? [true])
nil
1:23 user=> (find-first-r
