>* That wasn't my point either. My point is that since arrays and nested
*>* lists are treated as interchangeable in many situations, it makes
*>* sense to use this analogy as much as possible and allow an indexing
*>* scheme for arrays that matches that for nested arrays. WHich means
*>* that it should always be allowed to have just one index, independent
*>* of the rank of the array.

This is sort of irrelevant, but it has occured to me, now that I
understand and really like [::-1], I was sort of hoping that I could do
the same with lists. How easy would it be to extend that third argument
to list slices?
