looper = (0..3).cycle
20.times { puts looper.next }

can I somehow find the next of 3? I mean if I can get .next of any particular element at any given time. Not just display loop that starts with the first element.

UPDATE Of course I went though ruby doc before posting my question. But I did not find answer there ...
