Compute the cartesian product of an array. To do that, you can either make the array global or declare the array with the static keyword. APL has a built-in outer product operator: X ∘.F Y will get you an ⍴X-by-⍴Y matrix containing every corresponding value of x F y for all x∊X, y∊Y. This operation is called the Cartesian product. The rest, we consider lower priority. - In Pursuit of Laziness /// let lists: &[&[_]] = &[&[1, 2], &[4, 5], &[6, 7]]; /// let product = cartesian_product(lists); /// assert_eq!

Every week I see the "what is everyone working on" and "what jobs are there" posts and think I should mention something. Sometimes, you just need to compute very large cartesian products just so you can use a handful of the indexes from the result.
