[Numpy-discussion] numpy.fftpack: axis=None ?

[PGM]

Folks,
I was playing around the numpy.fftpack when I ran into the problem below:
it seems that axis=None is not valid with fft. Is there a reason for that ? I 
was assuming a behavior similar to other functions, where axis=None 
translates to "use a flat array".

_fft_cache)

     47         s = list(a.shape)
     48         if s[axis] > n:

TypeError: tuple indices must be integers
