Hi, In the LHS of a rule, could I bind to a variable a object that is returned from a method called on a matched fact ? (rule x (theShadowfact ?o) (... ?o getXYZ ... ) The purpose of doing this is to have a variable on which to do some tests without having to call getXYZ for each one of them. Thanks
