Yes, but the reason why nD slices are is not included is likely for
efficiency reasons. Anyway, slices would not help. Excluding rows and
columns is another sort of operations.
I don't think the language should provide slices. It should provide means
to define operations using slice syntax instead.

No, that is low-level mess.
