> Calling {{numpy.asarray}} on an instance of {{Array/ChunkedArray/Column}}
> should call the {{to_pandas}} method of these classes. Currently it falls
> back to using the iterator interface, thus we will always get an {{object}}
> array of {{pa.lib.ScalarValue}}.
> To implement this, one has to implement the {{__array__}} method on all of
> them.
