Find the intersection of arrays a and b. The individual arrays are expected to be sets, i.e. there's no duplicate elements in them.
You can also pass an array of arrays as a single argument, to get the intersection of n` arrays.
This module contains an alternative intersection algorithm by @minuteman3, better suited for intersecting big arrays.
The implementations might compare like this, depending on your host environment:
