  Sorry, I completely missed this old exciting topic and posts.

Please could you develop a bit to show how we can create cycles using functional abstraction ?

 In fact, my problem is I do not exactly see what means "functional abstraction".

Do you speak about something like this ?

type circular_list = Circular_list of (unit -> circular_list)

let rec cl = fun () -> Circular_list (fun () -> Circular_list cl)
