Yep, sometime the tent just comes down in the middle
of a storm.
I recently gave up the prescriptive Java/XML
implementation of a WFMC (workflow management coalition)
compliant workflow management system (because of
language and paradigm limitations), and turned the
workflow system into a declarative CLIPS implementation
using Jess. (Our goal is to eventually provide the
implementation in SweetJess, Jess's XML cousin that uses
DAML+OIL and Rule ML so that we can program in "XML" and
satisfy what corporate America wants to hear:
"It is in Java and in XML"
we'll give them SweetJess :-) which is of course a
logical-functional Trojan horse.
Our code in Jess is about 1/5 of what it used to be and
I can do things that are nearly impossible using
the prescriptive and XML forms.
Did I mention that it is also mobile, concurrent safe,
and changeable at runtime (dynamic rules, functions, facts
created on the fly)?
The next release of Jess will add Lisp-like macros ....
Btw, does anyone know of a native CLIPS implementation in
Lisp? (Currently I added a PROLOG library to my lisp but
it doesn't quite feel like CLIPS.)

I needed features that were more akin to Curry (the
logical Haskell cousin). In fact, in the future
we are considering using the Xurry virtual machine (a logical-functional
virtual machine that sits on top of Java).
Some rough estimates indicate that our Xurry code will
be between 1/5 and 1/10 of what our original wfmc
prescriptive code used to look like,
