Subject: bug#39919: 26.3; Incorrect byte-compiler warning
Date: Wed, 4 Mar 2020 23:18:07 +0000

Compiling this minimal test:

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

(dotimes (i 10 t)
    (prin1 i))

Gives the incorrect warning: "Unused lexical variable ‘i’”, even though `i' is clearly used inside the loop.

However the following version (dropping the [result] form from `dotimes') does not give the warning:

(dotimes (i 10)
    (prin1 i))

This would seem like a bug to me.
Please advise?

Thanks,
Mike
