Just don't mention Electric Clojure, because that might cause some head explosions. (Fully reactive multi-tier programs where an entire web UI is 60 lines of code and implements infinite scroll with search and dynamic viewport resizing.)
If you know Clojure, the code presented in the example seems fairly straightforward. Parentheses demarcate the syntax tree; and the last expression in any tree is the result carried forward.
