What's the status of font-lock and derived.el in XEmacs nowadays,
regarding sync with GNU Emacs?
I've understood that font-lock may be a bit controversial topic, but
there are a couple of *-faces and the :inherit stuff that might be
useful to have in XEmacs also.
derived.el seems quite different in XEmacs from what it is in Emacs,
which makes it difficult to sync other modes since they seem to be using
it increasingly much and it seems to have some nice goodies. derived.el
is in core now, and a grep to the current source tree reveals that it is
(possibly) only in use in help.el and list-mode.el there. Would it be
possible/useful to move it into xemacs-base?
Also, I think an up to date easy-mmode.el should be included in some
package, preferably xemacs-base. There is a version of it in pcl-cvs,
but IMO that's not the correct place for it, and this version seems
pretty outdated.
Having these three up to date (with Emacs) would make it much easier to
sync other modes as well as incorporate new ones. It is _possible_ to
work around most of the missing functionality, but it certainly isn't
fun or beautiful :)
Comments?

I have run into problems with this being out of date every now and then
with tools that look very interesting.
It would be good to see someone sync it up. :)

Yeah, that'd be pretty nifty.

Anything's possible. But what do we gain from moving a piece of
dumped lisp into the packages?

Yep, no problem with doing this. I'll move the file then you can sync
it.

Faster approval and distribution of improvements, and all of the
versions that can use packages (ie, >=20.4) stay in synch (maybe ;-).
The con is that derived.el may want to use XEmacs internals.
I'd say that it would be real nice if Ville would look at packagizing
it, although it might not really be feasible to move it out of core.

Ok, I'll see if I can find time to do a (at least) partial sync soon.

Anything's possible. But what do we gain from moving a piece of
dumped lisp into the packages?
Well, the ability to actually _use_ the new functionality in packages
without having to worry about backwards compatibility for XEmacsen that
do not have the new stuff. Looking from the packages side, it would not
be too useful to update for example derived.el in XEmacs 21.5 with Emacs
21.2, since packages could still not use it as they have to support 21.1
and 21.4 too. Plus the usual benefits for lisp in packages vs in core;
quicker, better targeted change/bugfix/update cycle etc?
Ah, and for these reasons it would be nice to have font-lock in packages
too, but I see there is some C code (src/font-lock.c) related to it,
might be a trickier one to move? Maybe this is why font-lock is still
in core and not in fsf-compat or xemacs-base though many
font-lock-*-face docs say "It is present only for horrid FSF
compatibility reasons."?
By "possible" I meant stuff like what happens if an XEmacs with
dumped/in-core foo.el installs and uses a package with a new version of
foo.el? Warnings? Which version will actually be used? Other
problems?

Cool. I'll take a look after the move has happened.

If you require it, the preloaded version will be used. If you
load-library it, the package version should be used with the default
load-path.
You will get shadowing warnings at build time (maybe) and in bug
reports, but not in ordinary operation.
