Now that refer is part of require, I don't think the existing syntax is too
hard for new comers. The only thing I would suggest is adding the ability
to :rename to require. That is, now that :refer is in require, require can
handle anything except :rename and :exclude. I'm not concerned with
:exclude since IMO it probably does more harm than good. However, if one
wants to rename, one still has to use refer or use in the ns macro. If on
the other hand rename were added to require, we could forget about use and
refer entirely in the ns macro, which would simply things a lot for new
comers. (Of course, it would still be helpful for them to learn about use
and refer, but they could get quite far without knowing about them.) So
something like:
(:require [clojure.string :refer [reverse] :rename {join str-join}])
