Subject: bug#49407: Request: Specify default values in `map-let` in Map.el
Date: Sun, 04 Jul 2021 23:08:55 +0000 [thread overview]
Message-ID: <ba79f925-aa14-3d51-e888-7113e6cf09c4@protonmail.com> (raw)
Hello,
`map-let` allows one to conveniently bind variables using `map-elt`, but
does not provide a way specify a default value if a key is missing.
With `map-elt`, one can use the optional third argument to specify this
value. It would be good to have this in `map-let` as well.
For example, maybe it could look something like
;; As just a third value in the list:
(let ((map '(:a 1 :b 2)))
(map-let ((:a a)
(:b b)
(:c c 3))
map
(+ a b c)))
or
;; More like Common Lisp arg-list for `&key'.
(let ((map '(:a 1 :b 2)))
(map-let ((:a a)
(:b b)
(:c (c 3)))
map
(+ a b c)))
Please consider adding this feature.
Thank you.
