The most popular library in MELPA, https://github.com/magnars/dash.el,
implements it (for a long time) like this:

    (--map (* it it) '(1 2 3))
    ;; => (1 4 9)

With my approach, it's:

    (mapcar #(* % %) '(1 2 3))
    ;; => (1 4 9)

I've grepped the useage of `--map' in all > 150 third party packages
that depend on `dash'.
I got 203 total results 60 different packages. This says a lot about
people wanting this feature for a long time.
