quite similar to IRL, that bit, yes.
We don't want to shove S-expressions down peoples throught.
If enough people are interested, I could write something up on the
new DRL
languages and features (just as a sneak preview).

I hope we will have this work for all objects of a class also. For
example:
not Person()
which says, there is NO person.

yeah thats a really powerful feature, and is definately going to be
part of Drools 3.
It will work something like:
not Person(name == "michael")
which says, there is NO person called michael.
Of course, you can work around this now, either by baking some
of the
logic into your model, or looking through working memory (which is
possibly slower).

Michael.

Hey,
I've used rules engines in the past the support the notion of a
NOT
pattern/conditional element for firing rules when a particular
item
doesn't exist in working memory. Does Drools support such a
feature? I can't find it in the docs.
I want to apply the following logic:
IF there is an event object available
AND there is no existing event history object
THEN.
