you can do some pretty powerful things using update-in and merge-with,
especially if combined with protocols or multimethods that determine
behavior. Can you give a more specific example of what you're trying to do?
deep-merge and deep-merge-with are also useful here. There are a lot of
nearly identical implementations originally taken from
clojure.contrib.map-utils.

Another approach to look at would
be
https://github.com/clojure/clojurescript/blob/master/src/cljs/clojure/zip.cljs
(or the faster
https://github.com/akhudek/fast-zip/blob/master/src/cljs/fast_zip/core.cljs),
and maybe porting some of the functionality
of https://github.com/xsc/rewrite-clj to cljs.
Perhaps a combination of the two for first finding said arbitrary point in
your tree and then returning an edited version.
