Why use a doubly-linked-list here?  An allocating xarray should perform
much better and use less memory.

We don't expect the list to be too long. So we may not gain any significant
advantage in terms of performance or memory when using alternate lists. Since
linked list easier to use, we chose it.

It is not easier to use.
