This is *NOT* part of the array API spec (so it should not be relied on for portable code). However, without this, np.asarray(np.array_api.Array) produces an object array instead of doing the conversion to a NumPy array as expected. This would work once np.asarray() implements dlpack support, but until then, it seems reasonable to make the conversion work. Note that the reverse, calling np.array_api.asarray(np.array), already works because np.array_api.asarray() is just a wrapper for np.asarray().
