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... :)
