Given an input n, write a function always that returns a function which returns n. Ruby should return a lambda or a proc.

var three = always(3);
three(); // returns 3

three = always(3)
three() # returns 3

three = always(3)
three.call # returns 3

three = always(3)
three() /* returns 3 */

let three = always 3
three () -- returns 3

(def three (always 3))
(three) ;; returns 3

three = always(3)
three.() #=> 3

function<int (void)> three = always(3);
three(); // returns 3

Func<int> three = Kata.Always(3);
three(); // returns 3
