This question may sound shocking but I'll explain why I still ask it.
Now at the core of Emacs is ELisp, but should I dare to hope that this will
change some day? I mean, if I want to add a new programming mode to emacs
(graphical structograms etc. see X32 editor at
http://www.blue-river-software.com) I don't think I could write it in
ELisp.Maybe in Perl, Python or even C.
And there is another issue: if you want Emacs to stay alive in the future
then you should change it at its core. Look at the sentmail and qmail:
sendmail is cool, but very hard to configure, qmail is not. That's why so
many sites quit using sendmail for qmail.
If this is out of the question, then sory for the noise.
