[Ocaml-lib-devel] Fwd: Re: Obj module should provide binding for Double_field and Store_double_field macros (PR#3456)

See below.  It should be possible to use these to print out the

You can define them yourself:

let double_field x i = Array.get (Obj.obj x : float array) i;;
let store_double_field x i v = Array.set (Obj.obj x : float array) i v;;
