JESS: Multiple fact or's

[Henrique Lopes Cardoso]

Hi,

I have a rule looking like this:

(defrule
   ?b1 <- (t1 (s ?s1))
   ?b2 <- (t2 (s ?s2))
   (or (test (eq ?s1 x)) (test (eq ?s2 x)))
   =>
   ...)

This example simplifies the general case. I may have any number of
bindings, and the common slot 's' is checked to see if at least one of
the bound facts has a certain x value. Is there a more efficient way of
doing this? E.g. (member$ x (list ?b1 ?b2 ...)) ?

Thanks.

Henrique
