I just noticed you included 'reverse' in that list of methods. I thought junctions were inherently unordered, thus making reverse kind of useless (which leads me even more to believe that I've misunderstood the question).


Yes--Junction is a sister of Any, not a subtype of Any. That's how you get the autothreading--accept Any or a subtype thereof, and when you get a junction, you autothread. Accept Junction or Object and you can inspect the junction directly.

At least, that's how *I* think it works... :)
