Notice that even O'Caml itself (I mean without camlp4) already has this
problem:


        Objective Caml version 3.00+8 (2000-06-30)

# let x = [| 1 ; 2 |];;  
val x : int array = [|1; 2|]
# module Array = struct end;;
module Array : sig end
# x.(1);; (* guess what happens... *)
Unbound value Array.get
# (* x.(1) just expands to Array.get x 1 *)
