Do I understand your question right, that you want the return
of == to be false because there is a one(1,0,1) junction? As
Duncan points out junctions are immutable values and as such
the % autothreads but the resulting values are assembled into
a new junction according to the general rules, i.e. one(0,1).
The number of elements in one(1,2,3) is not preserved.
