Subject: bug#49116: 28.0.50; Why `bound-and-true-p' is not working in lexical binding?
Date: Sat, 19 Jun 2021 14:39:54 +0300 [thread overview]
Message-ID: <861r8yozg5.fsf@protected.rcdrun.com> (raw)
When I evaluate following it is not detecting variable `direction'
under lexical bindings:
(defun verify-direction (timestamp &optional direction)
(cond ((bound-and-true-p direction) (message "OK"))))
(verify-direction "10:00" t) ⇒ nil
I would like to understand if it is intended to be so?
Or is this possible bug?
