I think we are talking about here an *array protocol* (i.e. like the
buffer protocol and sequence
So far we have just described the Python level interface. I would like
to see an array protocol added (perhaps to the buffer protocol table).
This could be done just as David describes --- we don't even need to use
the C-pointer (just return a void *pointer which has a version as the
I think this is how the C-level should be handled, I think. Yes, it
does not require changes to Python to implement the __array_c__
attribute. But, ultimately, it would be better if we used the C-level
protocol concept that Python already uses for other objects.
