I am not following. What is the issue here?
up-list has always worked that way and it is a nice feature of emacs
that I use everybody.
Cheers,
Leo

A list can't start resp. end inside a commented section.

Sure it can. Just because it's behind a comment char doesn't mean it's
not a list.

From Elisp Info
2.2 Comments
============
A "comment" is text that is written in a program only for the sake of
humans that read the program, and that has no effect on the meaning of
the program. [...] The Lisp reader discards comments; they do not
become part of the Lisp objects which represent the program within the
Lisp system.
;;;
BTW being in favor to remove all syntax-fiddling from plain text modes
and fundamental-mode alike. Setting syntax there must produce
inconsistency and unexpected behavior.
An example: try M-x backward-sexp RET from end of a text-mode buffer
with contents:
1) Asdf
2) Asdf

The concept of a list is independent of any programming language, and
has nothing to do with the Lisp reader. Moreover, you can run
eval-last-sexp also inside a comment.

Hmm, didn't expect that and don't believe it. We speak about lists in
emacs-lisp here, it is defined what a list is. They affect there meaning
of a program and therefor can't exist inside a comment.
Moreover, you can run

Thanks, just another bug. As the info above tells contents of a comment
having no effect WRT meaning of a program, result of evaluation in this
case comes from the deepness of nothing? ;)

The request here is to make the navigational command `up-list' ignore
commented out text. From reading this thread, no one was very
enthusiastic about this proposal.
To the arguments presented by others for the correctness of this
behaviour, I can only add that the proposal would make the command
significantly less useful.
I'm therefore closing this as wontfix.
Best regards,
Stefan Kangas
