; defining a function to square a number
user=> (defn square [x] (* x x))
#'user/square
user=> (square 3)

; now using an anonymous function
user=> (def square2 (fn [x] (* x x)))
#'user/square2
user=> (square2 3)

; some more sugar for anonymous functions
user=> (#(* % %) 3) ; square
9
user=> (#(+ % (* 2 %2)) 1 3) ; 1*x + 2*y

user=> (+ 1 (* 2 3))
