You seem to be ignoring possiblities for sharing across lists, and such sharing is natural in many graph algorithms.

No doubt cons cells are a useful construct. I think Martin Blais (and others) advocated a plain list container type, only implemented as a linked list, instead of a as a vector. The subject is "deque alternative", after all.

Typically, you either have sharing, or you have appending, but not both. If sharing is what you want, 2-tuples (pairs) provide an adequate API (IMO). If you want a deque alternative, sharing won't happen.
