I have a question about this though.  The object "ndarr" will consist of
"records", e.g.:

   In [96]: type(ndarr[0])
   Out[96]: <class 'numpy.core.records.record'>

If ndarr had been defined directly via ndarray constructors, then you'd get:

   In [99]: type(ndarr[0])
   Out[99]: <type 'numpy.void'>

I guess this might not be such a big deal.   But what is the difference
between the "record" class nad the "void" class?    Does this matter for
anything at all?

Thanks
Dan
