Combine spreads like ABAB


I’m trying to combine two spreads, alternately taking one slice of each spread.
Cons just sticks them together (AABB) and while Stallone gives back ABAB it’s quite messy to sum up two Count nodes just to get the right spread size for the Stallone.

Is there a more elegant solution to this?

Vector (2d Join) is your friend

Thanks a lot! :)
