Yes. Consider:

    for (int i = 0; i < list.length; ++i)
          sum += list[i];

If indexing was allowed on a list, this would seem like perfectly reasonable code.

In many languages that is perfectly reasonable because list does not equal linked list. Its almost as if a list is an abstract concept and does not mean any one definite data structure, hmmm who wuda thunk that...

It's definitely true that the term list does not denote a particular data structure in computer science, so I disagree with Walter's reticence to use the term list with AliasList, but it's also true that some languages and libraries have stupidly put indexing on a linked list, which is what deadalnix was complaining about.
