We don't return a list or a tuple because other functions within mpl needs
the numpy array.

You might want to read up on numpy arrays. A slice of an array returns a
view. A slice on a view also returns a view. If you want a copy, the
array has a copy() method. I don't know if the copy module would actually
work because it would merely be copying the view (creating a duplicate
view).
