Named variables in common lisp

We can have named variables in commons lisp by using cl-defun and &key: 

(cl-defun my/example (&key param1 param2 param3)
  "This prints out the params values"
  (message "%s %s %s" param1 param2 param3))

(my/example
 :param1 "hello"
 :param2 "world"
 :param3 "emacs!")

Output: 

hello world emacs!

The order of the parameters doesn't matter when you're using keys: 

(my/example
 :param2 "world"
 :param1 "hello"
 :param3 "emacs!")

Output: 

hello world emacs!
