f2py wants to do the same thing, i.e., change the data pointer of an
existing array, which is why NPY_NO_DEPRECATED_API is not defined in that
module. I had some discussion off list with Pearu about that but it petered
out. I think for this sort of thing is a new function needs to be
implemented. What precisely is your application? IIRC, Pearu was using it
to exchange pointers between two arrays to avoid a copy.
