Subject: bug#68931: 30.0.50; Gnus byte-compilation error with (display . [not expire]) with git emacs
Date: Mon, 5 Feb 2024 15:00:36 +0100	[thread overview]
Message-ID: <523B7DE4-EA66-4686-845A-35CDCC575F92@gmail.com> (raw)
In-Reply-To: <86r0hr13eu.fsf@gnu.org>

>> Debugger entered--returning value: "Malformed function ‘#[0 \"\\301\\300!\\207\" [expire gnus-article-marked-p] 2]’"
...
>> * gnus-summary-display-make-predicate((not expire))

Apparently, gnus-category-make-function-1 creates code that isn't really valid Lisp but that we have previously allowed anyway: (F ...) where F is a (non-symbol) function value, instead of using `funcall`.

We could (and probably should) allow this for compatibility but perhaps it's time to at least start warning about it? It makes the quirky semantics of a Lisp-2 even quirkier.
