The flatiter object didn't have comparisons implemented so I guess it 
was using some default implementation.  This is quite confusing and 
option 2 does make sense (an array of resulting comparisions is returned).

Thus now:

 >> x=arange(3).flat
 >>> x>2
array([False, False, False], dtype=bool)
 >>> x>1
array([False, False, True], dtype=bool)
 >>> x>0
array([False, True, True], dtype=bool)
