For instance there could be a where-like function that returns an object that can generate a set of indexes on the fly, rather than explicitly allocating arrays and enumerating all of the indices.
What's the reason iterators are not supported currently?
For instance A[range(0,4)] works for a 1d A, but A[xrange(0,4)] does not. Are iterators just too inefficient to bother with?
I could imagine an iterator that generates a set of N-tuples for an N-d array being a legal indexing construct. Even something like A[idx_iterator] = value_iterator would seem to make sense.
