Yes, I know. What I meant was that perhaps since it wasn't part of the
subset of functionality common to all of the backends, that it would
be omitted from the interface entirely.

Now, however, I just suspect that numpy.fft just got a little more
development and no one though to implement it over in scipy.fftpack.
