You have the abstractions you need in the core, just wire them together: Enumerable#cycle, Enumerable#take and Enumerable#inject:
That’s the functional/declarative approach: use abstractions (either existing or those you implement yourself) so you can write code that describes what you are doing instead of how you are doing it.
