Actually, to an insider, some of the code in ILISP is
a bit terrifying too ;-)

Steve Haflich (of Franz) was the author of the very
first version of ELI back around 1987. Since then, a
number of different Franz hackers have contributed to
it.

I'm not sure which group you're referring to. As far
as I'm aware, there is no Franz/ELI mailing list on
groups.google.com. If you're referring to
comp.lang.lisp.franz, I'm not surprised as that
newsgroup is just about dead - most Franz-specific
issues seem to be either directed to c.l.l. or to the
allegro-cl mailing list, both of which are very active
and both of which you can generally get a quick reply
from.

That is a bit unfair. I have personally worked with
both Steve Haflich and Kevin Layer on various ELI
enhancements and have worked with a number of other
Franz employees on other ACL issues. I have always
found the Franz people I've dealt with to be very
receptive to suggestions as well as terrific
programmers. I doubt that you would get better
responses to requests or suggestions for improvements
at many open source projects. 

I should also mention that I am not a licensed ACL
user either.

I already mentioned that I use MS Windows - doesn't
that qualify me as playing on the dark side already
;-)

Aha, now come all the caveats: don't remove the label,
not valid with other offers, use before expiration
date, etc, etc :-)

Sorta like having a pint, eh - you can't just have one
:-)
