In [16]: np.iterable(1*ns)
Out[16]: 0
In [17]: np.iterable([1, 2, 3]*ns)
Out[17]: 1
huh.
So collections.Iterable tests for the presence of the iter method.
Value and friends have an iter method that raises a TypeError.
I don't know why. My guess is that if you don't implement iter, then under some circumstance python and/or numpy will try to iterate by calling getitem, which will do something stupid on a Value object.
