Subject: bug#29585: 26.0.90; Elint gives spurious warning with condition-case-unless-debug
Date: Tue, 05 Dec 2017 14:26:08 -0800

Wherever condition-case-unless-debug is used, elint will complain with:

use-package-core.el:1292:Warning: Not an error symbol in error handler: debug

This is due to the definition of condition-case-unless-debug:

--8<---------------cut here---------------start------------->8---
(defmacro condition-case-unless-debug (var bodyform &rest handlers)
  "Like `condition-case' except that it does not prevent debugging.
More specifically if `debug-on-error' is set then the debugger will be invoked
even if this catches the signal."
  (declare (debug condition-case) (indent 2))
  `(condition-case ,var
       ,bodyform
     ,@(mapcar (lambda (handler)
                 `((debug ,@(if (listp (car handler)) (car handler)
                              (list (car handler))))
                   ,@(cdr handler)))
               handlers)))
--8<---------------cut here---------------end--------------->8---

Maybe elint needs to be taught about this case?
