[Numpy-discussion] Arrays of poly1d objects, is this a bug?

Hi all,

I'm puzzled by this behavior a colleague ran into:

In [38]: p1=N.poly1d([1.])

In [39]: a=N.array([p1],dtype='O')

In [40]: a
Out[40]: array([], shape=(1, 0), dtype=object)

In [42]: print a
[]

In [43]: N.__version__
Out[43]: '1.0.2.dev3512'

He saw it running r3520 as well.

This looks like a bug to me,  since it seems impossible to make arrays
of poly1d objects:

In [44]: a=N.array([p1,p1],dtype='O')

In [45]: a
Out[45]: array([], shape=(2, 0), dtype=object)

In [46]: print a
[]


Any hints?

Thanks,

f
