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

Thanks All,
I am sorry I missed the issue. (I still can't seem to find it, actually.)
I agree that there would be minimal overhead here and I bet that would be
easy to show. I really look forward to seeing this get in!
Be Well

Whatever happened to duck typing?
Sigh.

I must say I don't understan
