An alternative is to write things like that as a function to take an
arbitrary number of elements, so that you could write:
intersection(a, b)
or
intersection(a,b,c,d,e)
That way people don't have to mentally verify that there isn't a
sneaky place in the middle where another function sneaks in, or
parentheses suggest a different order.
