closures - What is the equivalent of Let Over Lambda in Scala? -


i trying adapt "land of lisp" scala , got stuck elegant way lisp can support memoization using classic let on lambda pattern. here example counter in lisp:

(let ((count 0))   (defun add-one ()     (incf count)))

how in scala. came with

val addone = {    var count = 0    () => { count = count + 1; count } }

which don't find elegant. better proposals?
