I'm starting to think this box diagram would be helpful,
didn't one do a minimal example case with `nreverse' (or
`nconc'), i.e. the fewest number of lists and list elements
possible, and then draw a box diagram to show what happens?

I can do it in ASCII tonight, God willing, but I find it hard
to think that no one did it already?
