array() should accept empty lists in its arguments. Then array([])
would be a rank-1 array of length zero, array([[],[]]) a rank-2 array
of shape (2,0) and so on.  A single "empty array" does not make sense,
since there can be many empty arrays that differ in shape.  Matlab can
get away with that because its matrix concept is much more limited.
