Thanks for all of your work. Things seem to be shaping up nicely. I
just wanted to second some of the concerns below:
> Complex Types:
> 1) I don't like the idea of complex types being a separate subclass of
> ndarray. This makes them "different." Unless this "difference" can be
> completely hidden (which I doubt), I would prefer complex types to be on the
> same level as other numeric types.
> 2) Also, in your C-API, you have a different pointer to the imaginary data.
> I much prefer the way it is done currently to have complex numbers
> represented as an 8-byte, or 16-byte chunk of contiguous memory.
The second comment above is really critical for accessing utility
available in a very large number of numerical libraries. In my view
this would "break" the utility of numpy severely -- recopying arrays
both on the way out and the way in would be extremely cumbersome.
