But i have hetergenious arrays that have numbers and strings and NoneType, etc.

Take for instance:

In [11]: numpy.array([numpy.array([1,'A', None]),
numpy.array([2,2,'Some string'])], dtype=object)
Out[11]:
array([[1, A, None],
       [2, 2, Some string]], dtype=object)

In [12]: numpy.array([numpy.array([1,'A', None]),
numpy.array([2,2,'Some string'])], dtype=object).shape
Out[12]: (2, 3)

Works fine in Numeric and pre beta numpy but in beta numpy versions i get:

I think you want:

In [59]: a = array([array([1,'A', None],dtype=object),array([2,2,'Some string'],dtype=object)])

In [60]: a.shape
Out[60]: (2, 3)
 
Which makes good sense to me.
