Is that really true? From my original post:

>>> from timeit import Timer
>>> setup = "import Numeric; a = Numeric.arange(2000);a.shape=(1000,2)"
>>> Timer("for i in range(len(a)): row=a[i]", setup).timeit(number=100)
 0.12782907485961914
>>> setup = "import numarray; a = numarray.arange(2000);a.shape=(1000,2)"
>>> Timer("for i in range(len(a)): row=a[i]", setup).timeit(number=100)
 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.

Cheers,
