Hi Jonathan, This is an interesting point...since it was also my code :-D Had I known then what I know now from studying Jess's implementation, that Ernest actually tests the length of multislots as a condition of the pattern matching process, I would have opted for your shorter code. At the time, it seemed logical enough. My contention is that shortcuts are great if you understand their mechanics, else they introduce an unknown liability in your code.
