Hello,
Here's an example code:
(define-error 'unsupported-mode-error "Unsupported mode")
(condition-case e
(if (eq 'a 'a)
(message "test")
(signal 'unsupported-mode-error major-mode))
(unsupported-mode-error
(signal (car e) (cdr e)))
(error
(message "error")))
As you can see, I'm trying to re-throw some of the errors, so the variable `e' is used
inside `condition-case'. But I still get an "Unused lexical argument" warning.
regards,
Oleh

Yes, IIRC this bug was introduced in 24.1. It should be partially fixed
in 24.4 if you set byte-compile--use-old-handlers to nil. It should be
fixed in 25.1 where this var defaults to nil.
Can you confirm?
Stefan

I can confirm that this is fixed in 25.1, thanks. Sorry for the noise.
