I just wanted to add that getting the address as an integer is useful because one might actually want to do math with it. Since memoryviews also expose the shape, itemsize, and other information, it's conceivable that one might combine these with the base address to compute locations within the array. Example: take a memoryview, slice up the buffer into partitions and hand them off to worker functions running in a thread pool.
