I recall that I couldn't understand your post. That may just be me, but
I recall that no one else seemed to be able to understand your post
(including you), and my request for an example that actually compiles
has resulted in nothing so far.

Mathematically, lists are defined in terms of positions and insertions
and deletions. I don't know what you're talking about, but it isn't a
list.
