[Numpy-discussion] numarray zeros - keyword argument'typecode'

I just realized that
import numarray as na
and
from numarray import numeric as na

actually just differ in the definition of zeros() (and 3 other calls)

Hopefully I was the only one who missed this difference.
I thought that since numarray 0.5 everything was now in sub-packages and the
second way of doing the import was now the suggested one ...
Now I think otherwise and it makes all sense again.
