Subject: Re: Undefined behavior for the function ‘last’ or an error?
Date: Mon, 01 Apr 2024 13:12:37 -0400	[thread overview]
Message-ID: <87edbp9fcq.fsf@gmail.com> (raw)
In-Reply-To: <87il119g8u.fsf@gmail.com> (tpeplt@gmail.com's message of "Mon, 01 Apr 2024 12:53:21 -0400")

Forgot to mention -- these results are from Emacs version 29.3.

Start emacs from a shell prompt with "emacs -Q" to avoid any
re-definition of ‘last’.

> The built-in Emacs Lisp function ‘last’ accepts a list as its argument:
>
> (last '(a b c)) => (c)
>
> It also (surprisingly) accepts a non-list as its argument:
>
> (last 'a) => a
> (last 3.14) => 3.14
> (last "string of chars") => "string of chars"
