$ cat /tmp/letalist.el

;; -*- lexical-binding: t; -*-

(print

 (let-alist '((outer . ((inner . value))))

   (let-alist .outer .inner)))



$ emacs -Q -batch -f batch-byte-compile /tmp/letalist.el



In toplevel form:

/tmp/letalist.el:2:1:Warning: Unused lexical variable ‘\.inner’



This warning is incorrect because '.inner' is used in the inner

let-alist form.

I've attached a patch.
