At this point I'll give a plug for http://clojureatlas.com as a great
way to explore the Clojure core/libraries by concept.

Thanks, it was get-in that I was looking for, but couldn't find. Also
thanks to Dave for explaining that keywords have some internal magic
compared to strings. will remember!

Too true.

Yes, but really to GET a value nested IN a series of maps, he should
just be using get-in, rather than threading anything at all.

If you want that to work, you need something that creates ({"b" 1} "b") or
(get {"b" 1} "b")
for your example, I believe this works
(-> (hash-map "b" (hash-map :a 3)) (get "b") :a)
