Subject: lexical binding changes symbol standard-value property
Date: Wed, 29 Jun 2016 23:51:21 +1000 [thread overview]
Message-ID: <1467208281.2809432.651951793.477B9611@webmail.messagingengine.com> (raw)
Something strange is going on with lexical-binding and defcustom...
(defcustom dummy-var t
"This is a test var.")
;; => dummy-var
(car (get 'dummy-var 'standard-value))
;; => t
(setq lexical-binding t)
;; => t
(defcustom dummy-var t
"This is a test var.")
;; = dummy-var
(car (get 'dummy-var 'standard-value))
;; => (funcall (function (closure (t) nil t)))
Why is the standard-value property of dummy-var changing? I kinda need it to be consistent...
I can resolve with:
(eval (car (get 'dummy-var 'standard-value)
;; => t
...but not sure about using (eval ...)
Ideas?
