[Numpy-discussion] ndarray is not a sequence

Hello All,

The semantics of this seem quite insane to me:

In [1]: import numpy as np

In [2]: import collections

In [4]: isinstance(np.arange(5), collections.Sequence)
Out[4]: False

In [6]: np.version.full_version
Out[6]: '1.9.0.dev-eb40f65'

Is there any possibility that ndarray could inherit (in the last place)
from collections.Sequence?  It seems like this would only be a 1 - 5 line
fix somewhere.  I just spent a few hours tracking down a bug related to
this.  Thanks for considering!

Be Well
