Re: [Numpy-discussion] NA masks for NumPy are ready to test

Hi, Just some immediate minor observations that are really about trying to be consistent: 1) Could you keep the display of the NA dtype be the same as the array? For example, NA dtype is displayed as '>> a=np.array([[1,2,3,np.NA], [3,4,np.nan,5]]) >>> a array([[ 1., 2., 3., NA], [ 3.,
