Strange 'npy_array_list_free()'

[oysteijo]

Freeing a list does a lot of things. It frees everything
The array, the array->data, the filename, and the element itself.

In some cases the caller is not the owner of all this data, and then the caller will have to run their own solutions for freeing the lists. This requiers knowledge of the implementation etc. Is this code smell?

Maybe the libzip interface is just as convenient as the clumsy linked list structure? Maybe using npy_array_list should be discouraged? Or maybe not?
