 It seems that numpy cannot create recarrays from other numpy arrays:

 {{{
 >>> a=numpy.array([(1,3),(2,3)], dtype="i4,i4")
 >>> a
 array([(1, 3), (2, 3)],
       dtype='[('f0', '<i4'), ('f1', '<i4')]')
 >>> b=numpy.array([numpy.array([1,3]),numpy.array([2,3])], dtype="i4,i4")
 >>> b
 TypeError: expected a readable buffer object
 }}}

 In the same way, it should be nice to be able to put Numeric or numarray
 objects and not only numpy.
