More than appropriate in linear algebra, image processing, major
application areas of multidimensional arrays.

I do not see how a sequence is less a map position->element than
anything else.
In order to keep them separate there are types and interfaces. The
language must simply support them. A typical 1-D array would implement
both. A typical n-D array would possibly only one.
BTW, in image processing, for segmenting images I used to have them
sequenced. The sequence looked this way:
1 2 5 6 17 18 21 22
3 4 7 8 19 20 23 24
9 10 13 14 25 26 30 31
11 12 15 16 27 28 32 33
and so on. There are many sorts of algorithmically interesting mappings
from n-D to sequence.
