Is that really true? From my original post:

>>> from timeit import Timer
>>> setup =3D "import Numeric; a =3D Numeric.arange(2000);a.shape=3D(1000,2=
)"
>>> Timer("for i in range(len(a)): row=3Da[i]", setup).timeit(number=3D100)
 0.12782907485961914
>>> setup =3D "import numarray; a =3D numarray.arange(2000);a.shape=3D(1000=
,2)"
>>> Timer("for i in range(len(a)): row=3Da[i]", setup).timeit(number=3D100)
 1.2013700008392334

My post was from January, so, in the interim numarray has improved *a
lot* it's object creation time. In that case, why the numarray team
hasn't publisized that more? Well, I think I should be missing
something. Time for nap.
