Subject: bug#33314: 27.0.50; wrong compiler warning
Date: Thu, 8 Nov 2018 15:38:53 +0100	[thread overview]
Message-ID: <7ec0dc92-8e02-2060-3ca8-234ac3d7440e@online.de> (raw)

Get a compiler Warning: Unused lexical variable ‘regexp’

WRT a form like below:

(defun foo (regexp &optional something)
   "..."
   (unless (bobp)
     (when (empty-line-p) (skip-chars-backward " \t\r\n\f"))
     (let* ((orig (point))
	   (regexpvalue (if (eq regexp 'py-clause-re) (symbol-value 
'py-extended-block-or-clause-re) (symbol-value regexp)))
...

;;

As visible, regexp is evaluated in last clause.

Thanks,
Andreas
