[Caml-list] ocaml stream question

[Caml-list] ocaml stream question

[Garry Hodgson]

i'm playing with ocaml streams to build a lexer, using ocaml 3.02.  
trying the sample code:

     let next = function [< 'x >] -> x ;;

gets me:

     Characters 20-22:
     Syntax error

do i need to do something special to enable streams?
if i just do:

     let foo = [<>];;

it works ok, giving me:

     val foo : 'a Stream.t = <abstr> 

it appears to be the pattern match it doesn't like.

any clues for the clueless?

In OCaml, unlike Caml Light, you must use the keyword "parser":
       let next = parser [< 'x >] -> x ;;
