Subject: bug#24641: 26.0.50; let-alist: Incorrect byte-compile warning about unused lexical variable
Date: Sat, 08 Oct 2016 14:43:03 +0200	[thread overview]
Message-ID: <wvr4k2djypt4.fsf@phst-glaptop2.i-did-not-set--mail-host-address--so-tickle-me> (raw)


$ 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.
