Oh: Depending on your amibitions, it's worth thinking hard about i)

Further to my previous emails about getting SIMD aligned arrays, I've
noticed that numpy arrays aren't always naturally aligned either.
For example, numpy.float96 arrays are not always aligned on 12-byte
boundaries under 32-bit linux/gcc. Indeed, .alignment on the array

Hi Nathaniel,

The problem is that rule for arrays - and for every other party of
numpy in general - are that we *don't* pick types based on values.
Numpy always uses input types

Congratulation for the release and a big thanks for the hard work.

I'm trying to use numpydoc (Sphinx extension) for my project written in

First -- is this a matrix library, or a general use nd-array
library? That will drive your design a great deal.
This is very useful context - thanks! I've had opinions in favour of both an
nd-array style library and a matrix library. I guess it
Hi Nathaniel,
Sure. But the only reason this is in 1.6 is that the person who made
the change never mentioned it to anyone else, so it wasn't noticed
until after 1.6 came out. If it had gone through proper review/mailing
list discussion (like we're doing now) then it's very unlikely it

I'm hoping the API will be independent of storage format - i.e. the
underlying implementations can store the data any way they like. So the API
will be written in terms of abstractions, and the user will have the choice
of whatever concrete
