   (info "(elisp)Anonymous Functions"):

     In Lisp, a function is a list that starts with `lambda', a byte-code
     function compiled from such a list, or alternatively a primitive
     subr-object; names are "extra."

you can test this in *scratch*:

((lambda (n) (+ n (* n n))) 6)

(funcall (byte-compile (lambda (n) (+ n (* n n)))) 6)
