Subject: bug#26540: 25.2; [PATCH] Add cl-set-equal to test for set equality
Date: Mon, 17 Apr 2017 06:55:20 -0700 (PDT)	[thread overview]
Message-ID: <9502fe98-aed5-4474-aaed-5e88d5c1cd6f@default> (raw)
In-Reply-To: <87bmrve6n9.fsf@cassou.me>

> This patch adds cl-seq-equal to test whether two lists have the

> LIST2 and if every element of LIST2 also appears in LIST1.

Common Lisp (and the Emacs emulation) already has set
functions that do this - `[cl-]set-exclusive-or', for
example.
