[Numpy-discussion] str/bytes object from arr.data?

[Zachary Pincus]

As str objects are supposed to be immutable, I think anything  
"official" that makes a string from a numpy array is supposed to copy  
the data. But I think you can use ctypes to wrap a pointer and a  
length as a python string.
