I thought of something like binding the singleton fact to a

Comments, suggestions, criticisms?
No, that's the solution right there. The same object gets re-
asserted, so the binding doesn't get broken. Once a fact is asserted
in Jess, it's always represented by the same Java object, and its
numeric ID remains unchanged; both of these bits of info are useful
when building up structures out of facts.
