Comment(by skrah):

 Conversely, this array is currently rejected but should be allowed (I
 think):

 {{{
 >>> x = ndarray(buffer=bytearray(1), shape=[0], strides=[1], dtype="B")
 Traceback (most recent call last):
   File "<stdin>", line 1, in <module>
 ValueError: strides is incompatible with shape of requested array and size
 of buffer
 }}}


 But the rejected array can be created via a slice:

 {{{
 >>> x = ndarray(buffer=bytearray(1), shape=[1], strides=[1], dtype="B")
 >>> y = x[0:0]
 >>> y.shape == (0,)
 True
 >>> y.strides == (1,)
 True
 }}}
