RR> cedet is part of emacs 24 afaik but it's a huge monster. 

It's a 2 MB download, 8 MB when extracted.  I don't think that's "huge."

Remember, this is for backwards compatibility with people who don't have
a recent Emacs (23.1 or older).  XEmacs also has it.  Emacs 23.2 was
released in May 2010 and all the major distros have it.  So it's not
going to affect everyone.

Well, I'd like a decent class system.  I've "rolled up my own" enough
times and EIEIO has much better features than the CL defstructs.  I
don't want to keep reimplementing EIEIO features when I could be
improving Gnus.

If there's something better than EIEIO I'm all ears.
