I have obtained:

> Caml Light version 0.7mac

#let rec from n =3D [< 'n ; from (n+1) >] ;;
from : int -> int stream =3D <fun>
#let rec version1 flot =3D match flot with
[< 'n >] -> [< '(2*n) ; version1 flot >] ;;
version1 : int stream -> int stream =3D <fun>
#version1 (from 0) ;;
- : int stream =3D <abstr>
#let rec version2 flot =3D match flot with
[< 'n ; version2 reste >] -> [< '(2*n) ; reste >] ;;
version2 : int stream -> int stream =3D <fun>
#version2 (from 0) ;;
Uncaught exception: Out_of_memory
#

Why ??
Thank's for the answer.
