[Python-Dev] Fw: Behavior of buffer()

That's how the buffer API was supposed to be used.

I don't understand what you say, but I believe you.

Good idea.  (I guess right now you can see if calling buffer() with an
instance as argument works. :-)

Maybe you would like to work on a requirements gathering for a memory
object?
