 Luc, you use Linux, don't you ?
 Under Windows, I have:

        Objective Caml version 3.06

# let hd = function
    [] -> failwith "hd"
  | a::l -> a;;
Characters 2-3:
    | a::l -> a;;
    ^
Syntax error
# 

 This problem typically comes under Windows when you do a "cut and
paste" from a text editor to OcamlWin.exe. To overcome this problem, you
have to copy and paste your function one line at a time.
 To avoid making myself nervous, I simply never use OCamlWin.exe (or I
use an older distribution, like the 3.01 one). I prefer to run ocaml in
a "command" windows (in which case it is possible to cut and paste).

 Cheers,

 Sebastien.
