Jess has always worked this way. Beans are exactly like Facts, which
behave exactly as they did in CLIPS. We've talked about changing this
behavior, and that might happen, but it wouldn't be free. Either facts
would have to change, too, or you'd lose some of the nice symmetry
that exists now. It's too radical of a change to be a runtime option.

Of course, every time I say something like this in public, the next
day I think of a way to do it anyway...
