Sujet : Re: [Caml-list] forbidden construct as right hand side of "let rec"

While we are at it, what is the best way to convert a "straight" list
into a cyclic list?

i.e. convert

let l = a::b::[]

into

let rec l = a::b::l

(for arbitrary length lists). (The answer I recall from the archives
was using Obj.magic to mutate the [] in the original list).
