> Creating a MapArray from a python sequence currently requires lists of tuples
> as values:
> {code}
> arr = pa.array([[('a', 1), ('b', 2)], [('c', 3)]], pa.map_(pa.string(),
> pa.int64()))
> {code}
> While I think it makes sense that the following could also work (using dicts
> instead):
> {code}
> arr = pa.array([{'a': 1, 'b': 2}, {'c': 3}], pa.map_(pa.string(), pa.int64()))
> {code}
