This may be a silly question, but I had taken the non-self-joining nature of Drools for granted.  Aside from disabling the option in RuleBaseConfiguration, how would one write a rule that would not self-join (ie. the old behavior)?

(Say I wanted two different facts to match:
when
Foo()
Foo()
instead of the new default which allows the same fact to match)

Thanks.

   Michael,

   In 3.1 the default is now to allow self joins (we need to add BIG
warnings to the documentation due to this change) and an option was
added to RuleBaseConfiguration to remove self joins.
