An important difference is that in a sequence you can insert or
delete in the middle *shifting indices of all following elements*,
where in a dictionary such operation would not make sense.

Of course it does not imply that I would make a difference in syntax
of accessing elements. When dictionaries and sequences are treated
as immutable, they are very similar.
