well... just explore the good part (extremely flexible, concise syntax, compile-time metaprogramming) and the bad part (dynamic type, impure, sometimes too much parentheses) of Lisp, nothing fancy here.

Example

(defmacro when
  [test & body]
  `(if ~test (do ~@body)))

(ƒ non-sense
  [y]
  (λ [x] (when y (prn "y ⇔ ⊤") x)))

((non-sense true) 3)
