Function array_item_asarray

* C-level integer indexing always returning an array and never a scalar. * Works also for subclasses, but it will not be called on one from the * Python API. * * This function does not accept negative indices because it is called by * PySequence_GetItem (through array_item) and that converts them to * positive indices. */
