Ah, okay, so the practical advantage is that there are non-numpy consumers of the buffer interface starting to pop up, so the advantage is that rpy2 will interoperate with them too, without having to create a numpy array in between? That makes sense, and is good to know; thanks. -- Nathaniel ------------------------------------------------------------------------------ SOLARIS 10 is the OS for Data Centers - provides features such as DTrace, Predictive Self Healing and Award Winning ZFS.
