You are thinking of numarrays as python lists. They are much more like C
arrays: homogeneous, fixed-size structures. That's why things can be done
fast with them, but the price you pay is flexibility. If you need to grow a
numarray, the easiest way is to allocate a new one of the desired final size,
then copy into it the data of the original and fill in the new data as
needed. With judicious use of take & friends all this can be done
efficiently.
