  `zip' takes two arrays, iterates over `0...elems' and takes entries
  from both arrays, stores them in third array & returns that.

  ┌────
  │ # zip takes two arrays and returns a list.
  │ sub zip(@a, @b --> List) {
  │     die if @a.elems !== @b.elems;
  │     my @c;
  │     @c.push(@a[$_], @b[$_]) for ^@a.elems;
  │     return @c;
  │ }
