Subject: [PATCH] seq.el: add seq-last for symmetry with seq-first
Date: Tue, 14 Mar 2023 13:55:03 +0100 [thread overview]
Message-ID: <871qlrmr14.fsf@gmail.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 202 bytes --]
Sometimes I want to get the last element of sequence and
(seq-elt seq (1- (seq-length seq)) adds too much noise.
This patch adds a simple wrapper around that.
