I think changing the base type is bound to cause issues. For example,
suppose someone expects to be able to simply iterate over the array.
If they're assuming it's a list, they will expect the values to be
returned. If it's a dictionary, the keys will be. If you're going to
do that, you'd need to do a custom dict class that iterated over the
values I think.
