(Author here) Thanks for the time you put into your comment.

I think there may be both advantages and disadvantages in unifying function calls and dictionary queries. The reason I am asking the question is that I haven't been able to try it for myself (or at least read about someones experience with it).

And I will try exposing myself to more languages :-)

In Clojure, hash maps are functions of their keys. If you use keywords as keys, then keywords are also functions of maps.

    ({:a 1} :a)
    => 1

    (:a {:a 1})
    => 1

    (map {2 4} [1 2 3])
    => (nil 4 nil)

    (map {:a 1 :b 2 :c 3} [:a :b :c])
    => (1 2 3)

Thank you! One more reason to use Clojure...
