Hi Mark, Having an `out` might make sense. With present numpy, if you are really dealing with a file or file-like object, you might consider using `np.memmap` to access the data more directly. If it is something that looks more like a buffer, `np.frombuffer` may be useful (that doesn't copy data, but points the array at the memory that holds the buffer).
