file method readinto and buffer interface

[Florian Schulze]

Hi!

I would like to know why the file method readinto isn't documented and
might go away. I really like the idea of it. I saw it referenced only in
the new numarray where it is used to load data into an array.
Is it not pythonic?
I didn't see any good usage of the buffer interface, why is that so? I can
think of many cases where it could be used effectively. And why is there
now builtin function to get a writeable buffer object?

Regards,
Florian
