In other languages, curly braces are used to enclose executable
statements, so something like { println("Hello world\n"); } makes sense.
In Clojure, however, curly braces are used to enclose a list of key/value
pairs, aka a map. So when you say
{hash-map :c "Turd" :d "More Turd"}
you are creating a data structure with 2 and a half pairs. The first pair
uses the function hash-map as the key, and :c as the value; then "Turd" as
the next key and :d as the value; then "More Turd" as the last key, and no
value, causing the error.
