+### Cycle through an array.
+
+Each time the `printf` is called, the next array element is printed. When
+the print hits the last array element it starts from the first element
+again.
+
+```sh
+arr=(a b c d)
+printf '%s\n' "${arr[$((i==${#arr[@]}-1?i=0:++i))]}"

+### Toggle between two values.

+This works the same as above, this is just a different use case.
