I just tried making a sequence of junctions and found that each one ended up wrapped in a singleton list somehow:
> ({ 1 | -1 } ... *)[^3]
((any(1, -1)) (any(1, -1)) (any(1, -1)))
Strangely, I can set an ending condition that works like I would expect,
but the sequence still produces single lists.
> { (1|-1) * ++$ } ... -3
((any(1, -1)) (any(2, -2)) (any(3, -3)))
This seems to happen for any kind of junction, not just or-junctions.
Is this a bug, or some legitimate rule I'm unaware of?
