[Numpy-discussion] A couple of errors in numpy/records.py

[Francesc A. <fa...@ca...>]

Hi,

I've detected a couple of issues in records.py. For the first one, the
next should fix it:

     else:
         raise ValueError("Unknown input type")

Now, another curious thing (sorry, no patch this time):

In [6]: for i in numpy.rec.array([(1,2)], formats=3D'u4,u4'): print i
   ...:
(1L, 2L)

[No problem with this]

In [7]: for i in numpy.rec.array([(1,2)], formats=3D'u4,u4')[0]: print i
   ...:

I'd expect something like

1L
2L

Cheers,
