There's one special thing about it: the `buffer_info()` method returns a
tuple with the memory address and length (in items) of the current
underlying buffer. Pretty useless information in Python but handy in
extensions that can directly access the "raw" memory.

To the OP:  Since Python 2.5 the `ctypes` module is another way to
interface with "native" code in dynamic libraries from the standard
library.
