It's not clear to me that a 0-D array should be regarded
as a container holding a single item, rather than just an
item on its own.

Think about how you get from an N dimensional array to
an N-1 dimensional array: you index it, e.g.

   A2 = [[1, 2], [3, 4]] # a 2D array

   A1 = A2[1] # a 1D array

   A0 = A1[1] # a 0D array???

   print A0

What do you think this will print?
